-library.  On Unix, this command would typically be somethin like:
-
-cc -g -I$BDB_INSTALL/include -L$BDB_INSTALL/lib -o sample sample.c sample_test.c -ldb-4.8 -lpthread
-
-On Windows, you could use Visual Studio to create a project containing
-these files.
-
-Once the program is built, you can run it with no arguments.  The
-program generated from sample.sql will create a database environment
-in a directory named "numismatics."  This directory must be created
-before the program is run.

-**    YYCODETYPE         is the data type used for storing terminal
-**                       and nonterminal numbers.  "unsigned char" is
-**                       used if there are fewer than 250 terminals
-**                       and nonterminals.  "int" is used otherwise.
-**    YYNOCODE           is a number of type YYCODETYPE which corresponds
-**                       to no legal terminal or nonterminal number.  This
-**                       number is used to fill in empty slots of the hash 
-**                       table.
-**    YYFALLBACK         If defined, this indicates that one or more tokens
-**                       have fall-back values which should be used if the
-**                       original value of the token will not parse.
-**    YYACTIONTYPE       is the data type used for storing terminal
-**                       and nonterminal numbers.  "unsigned char" is
-**                       used if there are fewer than 250 rules and
-**                       states combined.  "int" is used otherwise.
-**    sqlite3ParserTOKENTYPE     is the data type used for minor tokens given 
-**                       directly to the parser from the tokenizer.
-**    YYMINORTYPE        is the data type used for all minor tokens.
-**                       This is typically a union of many types, one of

-**                       for base tokens is called "yy0".
-**    YYSTACKDEPTH       is the maximum depth of the parser's stack.  If
-**                       zero the stack is dynamically sized using realloc()
-**    sqlite3ParserARG_SDECL     A static variable declaration for the %extra_argument
-**    sqlite3ParserARG_PDECL     A parameter declaration for the %extra_argument
-**    sqlite3ParserARG_STORE     Code to store %extra_argument into yypParser
-**    sqlite3ParserARG_FETCH     Code to extract %extra_argument from yypParser
-**    YYNSTATE           the combined number of states.
-**    YYNRULE            the number of rules in the grammar
-**    YYERRORSYMBOL      is the code number of the error symbol.  If not
-**                       defined, then do no error processing.

-**
-** Suppose the action integer is N.  Then the action is determined as

-**
-**   0 <= N < YYNSTATE                  Shift N.  That is, push the lookahead

-**                                      slots in the yy_action[] table.
-**
-** The action table is constructed as a single large table named yy_action[].
-** Given state S and lookahead X, the action is computed as
-**
-**      yy_action[ yy_shift_ofst[S] + X ]
-**
-** If the index value yy_shift_ofst[S]+X is out of range or if the value
-** yy_lookahead[yy_shift_ofst[S]+X] is not equal to X or if yy_shift_ofst[S]
-** is equal to YY_SHIFT_USE_DFLT, it means that the action is not in the table
-** and that yy_default[S] should be used instead.  
-**
-** The formula above is for computing the action when the lookahead is
-** a terminal symbol.  If the lookahead is a non-terminal (as occurs after
-** a reduce action) then the yy_reduce_ofst[] array is used in place of
-** the yy_shift_ofst[] array and YY_REDUCE_USE_DFLT is used in place of
-** YY_SHIFT_USE_DFLT.
-**
-** The following are the tables generated in this section:
-**
-**  yy_action[]        A single table containing all actions.
-**  yy_lookahead[]     A table containing the lookahead for each entry in
-**                     yy_action.  Used to detect hash collisions.
-**  yy_shift_ofst[]    For each state, the offset into yy_action for
-**                     shifting terminals.
-**  yy_reduce_ofst[]   For each state, the offset into yy_action for
-**                     shifting non-terminals after a reduce.
-**  yy_default[]       Default action for each state.

-**
-** SQLite can be compiled with or without mutexes.  When

-** are enabled and SQLite is threadsafe.  When that macro is false,
-** the mutexes are omitted.  Without the mutexes, it is not safe
-** to use SQLite from more than one thread.
-**
-** There is a measurable performance penalty for enabling mutexes.
-** So if speed is of utmost importance, it makes sense to disable
-** the mutexes.  But for maximum safety, mutexes should be enabled.
-** The default behavior is for mutexes to be enabled.
-**
-** This interface can be used by a program to make sure that the
-** version of SQLite that it is linking against was compiled with
-** the desired setting of the SQLITE_THREADSAFE macro.

-** CAPI3REF: Closing A Database Connection {F12010}
-**
-** This routine is the destructor for the [sqlite3] object.  
-**
-** Applications should [sqlite3_finalize | finalize] all
-** [prepared statements] and
-** [sqlite3_blob_close | close] all [sqlite3_blob | BLOBs] 
-** associated with the [sqlite3] object prior

-**
-** INVARIANTS:

-**          allocated by a prior call to [sqlite3_open()],
-**          [sqlite3_open16()], or [sqlite3_open_v2()].
-**
-** {F12012} The [sqlite3_close()] function releases all memory used by the
-**          connection and closes all open files.
-**
-** {F12013} If the database connection contains
-**          [prepared statements] that have not been
-**          finalized by [sqlite3_finalize()], then [sqlite3_close()]
-**          returns [SQLITE_BUSY] and leaves the connection open.

-** {F12014} Giving sqlite3_close() a NULL pointer is a harmless no-op.
-**
-** LIMITATIONS:
-**
-** {U12015} The parameter to [sqlite3_close()] must be an [sqlite3] object
-**          pointer previously obtained from [sqlite3_open()] or the

-** CAPI3REF: One-Step Query Execution Interface {F12100}
-**
-** The sqlite3_exec() interface is a convenient way of running
-** one or more SQL statements without a lot of C code.  The
-** SQL statements are passed in as the second parameter to
-** sqlite3_exec().  The statements are evaluated one by one
-** until either an error or an interrupt is encountered or
-** until they are all done.  The 3rd parameter is an optional
-** callback that is invoked once for each row of any query results
-** produced by the SQL statements.  The 5th parameter tells where
-** to write any error messages.
-**
-** The sqlite3_exec() interface is implemented in terms of
-** [sqlite3_prepare_v2()], [sqlite3_step()], and [sqlite3_finalize()].
-** The sqlite3_exec() routine does nothing that cannot be done
-** by [sqlite3_prepare_v2()], [sqlite3_step()], and [sqlite3_finalize()].
-** The sqlite3_exec() is just a convenient wrapper.
-**
-** INVARIANTS:
-** 
-** {F12101} The [sqlite3_exec()] interface evaluates zero or more UTF-8
-**          encoded, semicolon-separated, SQL statements in the
-**          zero-terminated string of its 2nd parameter within the
-**          context of the [sqlite3] object given in the 1st parameter.
-**
-** {F12104} The return value of [sqlite3_exec()] is SQLITE_OK if all
-**          SQL statements run successfully.
-**
-** {F12105} The return value of [sqlite3_exec()] is an appropriate 
-**          non-zero error code if any SQL statement fails.
-**
-** {F12107} If one or more of the SQL statements handed to [sqlite3_exec()]
-**          return results and the 3rd parameter is not NULL, then
-**          the callback function specified by the 3rd parameter is
-**          invoked once for each row of result.
-**
-** {F12110} If the callback returns a non-zero value then [sqlite3_exec()]
-**          will aborted the SQL statement it is currently evaluating,
-**          skip all subsequent SQL statements, and return [SQLITE_ABORT].
-**          <todo>What happens to *errmsg here?  Does the result code for
-**          sqlite3_errcode() get set?</todo>
-**
-** {F12113} The [sqlite3_exec()] routine will pass its 4th parameter through
-**          as the 1st parameter of the callback.
-**
-** {F12116} The [sqlite3_exec()] routine sets the 2nd parameter of its
-**          callback to be the number of columns in the current row of
-**          result.
-**
-** {F12119} The [sqlite3_exec()] routine sets the 3rd parameter of its 
-**          callback to be an array of pointers to strings holding the
-**          values for each column in the current result set row as
-**          obtained from [sqlite3_column_text()].
-**
-** {F12122} The [sqlite3_exec()] routine sets the 4th parameter of its
-**          callback to be an array of pointers to strings holding the
-**          names of result columns as obtained from [sqlite3_column_name()].
-**
-** {F12125} If the 3rd parameter to [sqlite3_exec()] is NULL then
-**          [sqlite3_exec()] never invokes a callback.  All query
-**          results are silently discarded.
-**
-** {F12128} If an error occurs while parsing or evaluating any of the SQL
-**          statements handed to [sqlite3_exec()] then [sqlite3_exec()] will
-**          return an [error code] other than [SQLITE_OK].
-**
-** {F12131} If an error occurs while parsing or evaluating any of the SQL
-**          handed to [sqlite3_exec()] and if the 5th parameter (errmsg)
-**          to [sqlite3_exec()] is not NULL, then an error message is
-**          allocated using the equivalent of [sqlite3_mprintf()] and
-**          *errmsg is made to point to that message.
-**
-** {F12134} The [sqlite3_exec()] routine does not change the value of
-**          *errmsg if errmsg is NULL or if there are no errors.
-**
-** {F12137} The [sqlite3_exec()] function sets the error code and message
-**          accessible via [sqlite3_errcode()], [sqlite3_errmsg()], and
-**          [sqlite3_errmsg16()].
-**
-** LIMITATIONS:
-**
-** {U12141} The first parameter to [sqlite3_exec()] must be an valid and open
-**          [database connection].
-**
-** {U12142} The database connection must not be closed while
-**          [sqlite3_exec()] is running.
-** 
-** {U12143} The calling function is should use [sqlite3_free()] to free
-**          the memory that *errmsg is left pointing at once the error
-**          message is no longer needed.
-**
-** {U12145} The SQL statement text in the 2nd parameter to [sqlite3_exec()]

-**
-** The zName field holds the name of the VFS module.  The name must

-** {F11141} SQLite will guarantee that the zFilename string passed to

-**
-** The file I/O implementation can use the object type flags to
-** changes the way it deals with files.  For example, an application

-** 
-** SQLite might also add one of the following flags to the xOpen
-** method:
-** 
-** <ul>
-** <li> [SQLITE_OPEN_DELETEONCLOSE]
-** <li> [SQLITE_OPEN_EXCLUSIVE]
-** </ul>
-** 
-** {F11145} The [SQLITE_OPEN_DELETEONCLOSE] flag means the file should be
-** deleted when it is closed.  {F11146} The [SQLITE_OPEN_DELETEONCLOSE]
-** will be set for TEMP  databases, journals and for subjournals. 
-** {F11147} The [SQLITE_OPEN_EXCLUSIVE] flag means the file should be opened
-** for exclusive access.  This flag is set for all files except
-** for the main database file. {END}
-**

-** allocate the structure; it should just fill it in.
-** 
-** {F11149} The flags argument to xAccess() may be [SQLITE_ACCESS_EXISTS] 
-** to test for the existance of a file,
-** or [SQLITE_ACCESS_READWRITE] to test to see
-** if a file is readable and writable, or [SQLITE_ACCESS_READ]
-** to test to see if a file is at least readable.  {END} The file can be a 
-** directory.
-** 
-** {F11150} SQLite will always allocate at least mxPathname+1 bytes for
-** the output buffers for xGetTempname and xFullPathname. {F11151} The exact
-** size of the output buffer is also passed as a parameter to both 
-** methods. {END} If the output buffer is not large enough, SQLITE_CANTOPEN
-** should be returned. As this is handled as a fatal error by SQLite,

-** If the busy callback is NULL, then [SQLITE_BUSY]
-** or [SQLITE_IOERR_BLOCKED]
-** is returned immediately upon encountering the lock.
-** If the busy callback is not NULL, then the
-** callback will be invoked with two arguments.  The
-** first argument to the handler is a copy of the void* pointer which
-** is the third argument to this routine.  The second argument to
-** the handler is the number of times that the busy handler has
-** been invoked for this locking event.   If the
-** busy callback returns 0, then no additional attempts are made to
-** access the database and [SQLITE_BUSY] or [SQLITE_IOERR_BLOCKED] is returned.
-** If the callback returns non-zero, then another attempt
-** is made to open the database for reading and the cycle repeats.
-**
-** The presence of a busy handler does not guarantee that
-** it will be invoked when there is lock contention.
-** If SQLite determines that invoking the busy handler could result in
-** a deadlock, it will go ahead and return [SQLITE_BUSY] or
-** [SQLITE_IOERR_BLOCKED] instead of invoking the
-** busy handler.
-** Consider a scenario where one process is holding a read lock that
-** it is trying to promote to a reserved lock and
-** a second process is holding a reserved lock that it is trying
-** to promote to an exclusive lock.  The first process cannot proceed
-** because it is blocked by the second and the second process cannot
-** proceed because it is blocked by the first.  If both processes
-** invoke the busy handlers, neither will make any progress.  Therefore,
-** SQLite returns [SQLITE_BUSY] for the first process, hoping that this
-** will induce the first process to release its read lock and allow
-** the second process to proceed.
-**
-** The default busy callback is NULL.
-**
-** The [SQLITE_BUSY] error is converted to [SQLITE_IOERR_BLOCKED]
-** when SQLite is in the middle of a large transaction where all the
-** changes will not fit into the in-memory cache.  SQLite will
-** already hold a RESERVED lock on the database file, but it needs
-** to promote this lock to EXCLUSIVE so that it can spill cache
-** pages into the database file without harm to concurrent
-** readers.  If it is unable to promote the lock, then the in-memory
-** cache will be left in an inconsistent state and so the error
-** code is promoted from the relatively benign [SQLITE_BUSY] to
-** the more severe [SQLITE_IOERR_BLOCKED].  This error code promotion
-** forces an automatic rollback of the changes.  See the

-** values are give a NULL pointer.  All other values are in

-**
-** There are two column (M==2) and three rows (N==3).  Thus the

-** CAPI3REF: Formatted String Printing Functions {F17400}
-**
-** These routines are workalikes of the "printf()" family of functions
-** from the standard C library.
-**
-** The sqlite3_mprintf() and sqlite3_vmprintf() routines write their
-** results into memory obtained from [sqlite3_malloc()].
-** The strings returned by these two routines should be
-** released by [sqlite3_free()].   Both routines return a
-** NULL pointer if [sqlite3_malloc()] is unable to allocate enough
-** memory to hold the resulting string.
-**
-** In sqlite3_snprintf() routine is similar to "snprintf()" from
-** the standard C library.  The result is written into the
-** buffer supplied as the second parameter whose size is given by
-** the first parameter. Note that the order of the
-** first two parameters is reversed from snprintf().  This is an
-** historical accident that cannot be fixed without breaking
-** backwards compatibility.  Note also that sqlite3_snprintf()
-** returns a pointer to its buffer instead of the number of
-** characters actually written into the buffer.  We admit that
-** the number of characters written would be a more useful return
-** value but we cannot change the implementation of sqlite3_snprintf()
-** now without breaking compatibility.
-**
-** As long as the buffer size is greater than zero, sqlite3_snprintf()
-** guarantees that the buffer is always zero-terminated.  The first
-** parameter "n" is the total size of the buffer, including space for
-** the zero terminator.  So the longest string that can be completely
-** written will be n-1 characters.
-**
-** These routines all implement some additional formatting
-** options that are useful for constructing SQL statements.
-** All of the usual printf formatting options apply.  In addition, there
-** is are "%q", "%Q", and "%z" options.
-**
-** The %q option works like %s in that it substitutes a null-terminated
-** string from the argument list.  But %q also doubles every '\'' character.
-** %q is designed for use inside a string literal.  By doubling each '\''
-** character it escapes that character and allows it to be inserted into
-** the string.
-**
-** For example, so some string variable contains text as follows:
-**
-** <blockquote><pre>
-**  char *zText = "It's a happy day!";
-** </pre></blockquote>
-**
-** One can use this text in an SQL statement as follows:
-**
-** <blockquote><pre>
-**  char *zSQL = sqlite3_mprintf("INSERT INTO table VALUES('%q')", zText);
-**  sqlite3_exec(db, zSQL, 0, 0, 0);
-**  sqlite3_free(zSQL);
-** </pre></blockquote>
-**
-** Because the %q format string is used, the '\'' character in zText
-** is escaped and the SQL generated is as follows:
-**
-** <blockquote><pre>
-**  INSERT INTO table1 VALUES('It''s a happy day!')
-** </pre></blockquote>
-**
-** This is correct.  Had we used %s instead of %q, the generated SQL
-** would have looked like this:
-**
-** <blockquote><pre>
-**  INSERT INTO table1 VALUES('It's a happy day!');
-** </pre></blockquote>
-**
-** This second example is an SQL syntax error.  As a general rule you
-** should always use %q instead of %s when inserting text into a string 
-** literal.
-**
-** The %Q option works like %q except it also adds single quotes around
-** the outside of the total string.  Or if the parameter in the argument
-** list is a NULL pointer, %Q substitutes the text "NULL" (without single
-** quotes) in place of the %Q option. {END}  So, for example, one could say:
-**
-** <blockquote><pre>
-**  char *zSQL = sqlite3_mprintf("INSERT INTO table VALUES(%Q)", zText);
-**  sqlite3_exec(db, zSQL, 0, 0, 0);
-**  sqlite3_free(zSQL);
-** </pre></blockquote>
-**
-** The code above will render a correct SQL statement in the zSQL
-** variable even if the zText variable is a NULL pointer.
-**
-** The "%z" formatting option works exactly like "%s" with the
-** addition that after the string has been read and copied into
-** the result, [sqlite3_free()] is called on the input string. {END}

-** CAPI3REF: Memory Allocation Subsystem {F17300}
-**
-** The SQLite core  uses these three routines for all of its own
-** internal memory allocation needs. "Core" in the previous sentence
-** does not include operating-system specific VFS implementation.  The
-** windows VFS uses native malloc and free for some operations.
-**
-** The sqlite3_malloc() routine returns a pointer to a block
-** of memory at least N bytes in length, where N is the parameter.
-** If sqlite3_malloc() is unable to obtain sufficient free
-** memory, it returns a NULL pointer.  If the parameter N to
-** sqlite3_malloc() is zero or negative then sqlite3_malloc() returns
-** a NULL pointer.
-**
-** Calling sqlite3_free() with a pointer previously returned
-** by sqlite3_malloc() or sqlite3_realloc() releases that memory so
-** that it might be reused.  The sqlite3_free() routine is
-** a no-op if is called with a NULL pointer.  Passing a NULL pointer
-** to sqlite3_free() is harmless.  After being freed, memory
-** should neither be read nor written.  Even reading previously freed
-** memory might result in a segmentation fault or other severe error.
-** Memory corruption, a segmentation fault, or other severe error
-** might result if sqlite3_free() is called with a non-NULL pointer that
-** was not obtained from sqlite3_malloc() or sqlite3_free().
-**
-** The sqlite3_realloc() interface attempts to resize a
-** prior memory allocation to be at least N bytes, where N is the
-** second parameter.  The memory allocation to be resized is the first
-** parameter.  If the first parameter to sqlite3_realloc()
-** is a NULL pointer then its behavior is identical to calling
-** sqlite3_malloc(N) where N is the second parameter to sqlite3_realloc().
-** If the second parameter to sqlite3_realloc() is zero or
-** negative then the behavior is exactly the same as calling
-** sqlite3_free(P) where P is the first parameter to sqlite3_realloc().
-** Sqlite3_realloc() returns a pointer to a memory allocation
-** of at least N bytes in size or NULL if sufficient memory is unavailable.
-** If M is the size of the prior allocation, then min(N,M) bytes
-** of the prior allocation are copied into the beginning of buffer returned
-** by sqlite3_realloc() and the prior allocation is freed.
-** If sqlite3_realloc() returns NULL, then the prior allocation
-** is not freed.
-**
-** The memory returned by sqlite3_malloc() and sqlite3_realloc()
-** is always aligned to at least an 8 byte boundary. {END}
-**
-** The default implementation
-** of the memory allocation subsystem uses the malloc(), realloc()
-** and free() provided by the standard C library. {F17382} However, if 
-** SQLite is compiled with the following C preprocessor macro
-**
-** <blockquote> SQLITE_MEMORY_SIZE=<i>NNN</i> </blockquote>
-**
-** where <i>NNN</i> is an integer, then SQLite create a static
-** array of at least <i>NNN</i> bytes in size and use that array
-** for all of its dynamic memory allocation needs. {END}  Additional
-** memory allocator options may be added in future releases.
-**
-** In SQLite version 3.5.0 and 3.5.1, it was possible to define
-** the SQLITE_OMIT_MEMORY_ALLOCATION which would cause the built-in
-** implementation of these routines to be omitted.  That capability
-** is no longer provided.  Only built-in memory allocators can be
-** used.
-**
-** The windows OS interface layer calls
-** the system malloc() and free() directly when converting
-** filenames between the UTF-8 encoding used by SQLite
-** and whatever filename encoding is used by the particular windows
-** installation.  Memory allocation errors are detected, but

-** any value other than [SQLITE_IGNORE], [SQLITE_OK], or [SQLITE_DENY]
-** then [sqlite3_prepare_v2()] or equivalent call that triggered
-** the authorizer will fail with an error message.
-**
-** When the callback returns [SQLITE_OK], that means the operation

-** CAPI3REF: Tracing And Profiling Functions {F12280}
-**
-** These routines register callback functions that can be used for
-** tracing and profiling the execution of SQL statements.
-**
-** The callback function registered by sqlite3_trace() is invoked at
-** various times when an SQL statement is being run by [sqlite3_step()].
-** The callback returns a UTF-8 rendering of the SQL statement text
-** as the statement first begins executing.  Additional callbacks occur
-** as each triggersubprogram is entered.  The callbacks for triggers
-** contain a UTF-8 SQL comment that identifies the trigger.
-** 
-** The callback function registered by sqlite3_profile() is invoked
-** as each SQL statement finishes.  The profile callback contains
-** the original statement text and an estimate of wall-clock time
-** of how long that statement took to run.
-**
-** The sqlite3_profile() API is currently considered experimental and
-** is subject to change or removal in a future release.
-**
-** The trigger reporting feature of the trace callback is considered
-** experimental and is subject to change or removal in future releases.
-** Future versions of SQLite might also add new trace callback

-** CAPI3REF: Opening A New Database Connection {F12700}
-**
-** These routines open an SQLite database file whose name
-** is given by the filename argument.
-** The filename argument is interpreted as UTF-8
-** for [sqlite3_open()] and [sqlite3_open_v2()] and as UTF-16
-** in the native byte order for [sqlite3_open16()].
-** An [sqlite3*] handle is usually returned in *ppDb, even
-** if an error occurs.  The only exception is if SQLite is unable
-** to allocate memory to hold the [sqlite3] object, a NULL will
-** be written into *ppDb instead of a pointer to the [sqlite3] object.
-** If the database is opened (and/or created)
-** successfully, then [SQLITE_OK] is returned.  Otherwise an
-** error code is returned.  The
-** [sqlite3_errmsg()] or [sqlite3_errmsg16()]  routines can be used to obtain
-** an English language description of the error.
-**
-** The default encoding for the database will be UTF-8 if
-** [sqlite3_open()] or [sqlite3_open_v2()] is called and
-** UTF-16 in the native byte order if [sqlite3_open16()] is used.
-**
-** Whether or not an error occurs when it is opened, resources
-** associated with the [sqlite3*] handle should be released by passing it
-** to [sqlite3_close()] when it is no longer required.
-**
-** The [sqlite3_open_v2()] interface works like [sqlite3_open()] 
-** except that it acccepts two additional parameters for additional control
-** over the new database connection.  The flags parameter can be
-** one of:
-**
-** <ol>
-** <li>  [SQLITE_OPEN_READONLY]
-** <li>  [SQLITE_OPEN_READWRITE]
-** <li>  [SQLITE_OPEN_READWRITE] | [SQLITE_OPEN_CREATE]
-** </ol>
-**
-** The first value opens the database read-only. 
-** If the database does not previously exist, an error is returned.
-** The second option opens
-** the database for reading and writing if possible, or reading only if
-** if the file is write protected.  In either case the database
-** must already exist or an error is returned.  The third option
-** opens the database for reading and writing and creates it if it does
-** not already exist.
-** The third options is behavior that is always used for [sqlite3_open()]
-** and [sqlite3_open16()].
-**
-** If the 3rd parameter to [sqlite3_open_v2()] is not one of the
-** combinations shown above then the behavior is undefined.

-** in-memory database is created for the connection.  This in-memory
-** database will vanish when the database connection is closed.  Future
-** version of SQLite might make use of additional special filenames
-** that begin with the ":" character.  It is recommended that 
-** when a database filename really does begin with
-** ":" that you prefix the filename with a pathname like "./" to
-** avoid ambiguity.
-**
-** If the filename is an empty string, then a private temporary
-** on-disk database will be created.  This private database will be
-** automatically deleted as soon as the database connection is closed.
-**

-** [sqlite3_vfs] object that defines the operating system 
-** interface that the new database connection should use.  If the

-** object is used.
-**
-** <b>Note to windows users:</b>  The encoding used for the filename argument
-** of [sqlite3_open()] and [sqlite3_open_v2()] must be UTF-8, not whatever
-** codepage is currently defined.  Filenames containing international

-** CAPI3REF: Compiling An SQL Statement {F13010}
-**
-** To execute an SQL query, it must first be compiled into a byte-code
-** program using one of these routines. 
-**
-** The first argument "db" is an [database connection] 
-** obtained from a prior call to [sqlite3_open()], [sqlite3_open_v2()]
-** or [sqlite3_open16()]. 
-** The second argument "zSql" is the statement to be compiled, encoded
-** as either UTF-8 or UTF-16.  The sqlite3_prepare() and sqlite3_prepare_v2()
-** interfaces uses UTF-8 and sqlite3_prepare16() and sqlite3_prepare16_v2()
-** use UTF-16. {END}
-**
-** If the nByte argument is less
-** than zero, then zSql is read up to the first zero terminator.
-** If nByte is non-negative, then it is the maximum number of 
-** bytes read from zSql.  When nByte is non-negative, the
-** zSql string ends at either the first '\000' or '\u0000' character or 
-** the nByte-th byte, whichever comes first. If the caller knows
-** that the supplied string is nul-terminated, then there is a small
-** performance advantage to be had by passing an nByte parameter that 
-** is equal to the number of bytes in the input string <i>including</i> 
-** the nul-terminator bytes.{END}
-**
-** *pzTail is made to point to the first byte past the end of the
-** first SQL statement in zSql.  These routines only compiles the first
-** statement in zSql, so *pzTail is left pointing to what remains
-** uncompiled.
-**
-** *ppStmt is left pointing to a compiled [prepared statement] that can be
-** executed using [sqlite3_step()].  Or if there is an error, *ppStmt is
-** set to NULL.  If the input text contains no SQL (if the input
-** is and empty string or a comment) then *ppStmt is set to NULL.
-** {U13018} The calling procedure is responsible for deleting the
-** compiled SQL statement
-** using [sqlite3_finalize()] after it has finished with it.
-**
-** On success, [SQLITE_OK] is returned.  Otherwise an 
-** [error code] is returned.
-**
-** The sqlite3_prepare_v2() and sqlite3_prepare16_v2() interfaces are
-** recommended for all new programs. The two older interfaces are retained
-** for backwards compatibility, but their use is discouraged.
-** In the "v2" interfaces, the prepared statement
-** that is returned (the [sqlite3_stmt] object) contains a copy of the 
-** original SQL text. {END} This causes the [sqlite3_step()] interface to
-** behave a differently in two ways:
-**
-** <ol>
-** <li>
-** If the database schema changes, instead of returning [SQLITE_SCHEMA] as it
-** always used to do, [sqlite3_step()] will automatically recompile the SQL
-** statement and try to run it again.  If the schema has changed in
-** a way that makes the statement no longer valid, [sqlite3_step()] will still
-** return [SQLITE_SCHEMA].  But unlike the legacy behavior, 
-** [SQLITE_SCHEMA] is now a fatal error.  Calling
-** [sqlite3_prepare_v2()] again will not make the
-** error go away.  Note: use [sqlite3_errmsg()] to find the text
-** of the parsing error that results in an [SQLITE_SCHEMA] return. {END}
-** </li>
-**
-** <li>
-** When an error occurs, 
-** [sqlite3_step()] will return one of the detailed 
-** [error codes] or [extended error codes]. 
-** The legacy behavior was that [sqlite3_step()] would only return a generic
-** [SQLITE_ERROR] result code and you would have to make a second call to
-** [sqlite3_reset()] in order to find the underlying cause of the problem.
-** With the "v2" prepare interfaces, the underlying reason for the error is
-** returned immediately.
-** </li>
-** </ol>

-**

-** CAPI3REF:  Binding Values To Prepared Statements {F13500}
-**
-** In the SQL strings input to [sqlite3_prepare_v2()] and its

-** of these forms:
-**
-** <ul>
-** <li>  ?
-** <li>  ?NNN
-** <li>  :VVV
-** <li>  @VVV
-** <li>  $VVV
-** </ul>
-**
-** In the parameter forms shown above NNN is an integer literal,
-** VVV alpha-numeric parameter name.
-** The values of these parameters (also called "host parameter names"
-** or "SQL parameters")
-** can be set using the sqlite3_bind_*() routines defined here.
-**
-** The first argument to the sqlite3_bind_*() routines always
-** is a pointer to the [sqlite3_stmt] object returned from
-** [sqlite3_prepare_v2()] or its variants. The second
-** argument is the index of the parameter to be set. The
-** first parameter has an index of 1.  When the same named
-** parameter is used more than once, second and subsequent
-** occurrences have the same index as the first occurrence. 
-** The index for named parameters can be looked up using the
-** [sqlite3_bind_parameter_name()] API if desired.  The index
-** for "?NNN" parameters is the value of NNN.
-** The NNN value must be between 1 and the compile-time
-** parameter SQLITE_MAX_VARIABLE_NUMBER (default value: 999).
-**
-** The third argument is the value to bind to the parameter.
-**
-** In those
-** routines that have a fourth argument, its value is the number of bytes
-** in the parameter.  To be clear: the value is the number of <u>bytes</u>
-** in the value, not the number of characters. 
-** If the fourth parameter is negative, the length of the string is
-** number of bytes up to the first zero terminator.
-**
-** The fifth argument to sqlite3_bind_blob(), sqlite3_bind_text(), and
-** sqlite3_bind_text16() is a destructor used to dispose of the BLOB or
-** string after SQLite has finished with it. If the fifth argument is
-** the special value [SQLITE_STATIC], then SQLite assumes that the
-** information is in static, unmanaged space and does not need to be freed.
-** If the fifth argument has the value [SQLITE_TRANSIENT], then
-** SQLite makes its own private copy of the data immediately, before
-** the sqlite3_bind_*() routine returns.
-**
-** The sqlite3_bind_zeroblob() routine binds a BLOB of length N that
-** is filled with zeros.  A zeroblob uses a fixed amount of memory
-** (just an integer to hold it size) while it is being processed.
-** Zeroblobs are intended to serve as place-holders for BLOBs whose
-** content is later written using 
-** [sqlite3_blob_open | increment BLOB I/O] routines. A negative
-** value for the zeroblob results in a zero-length BLOB.
-**
-** The sqlite3_bind_*() routines must be called after
-** [sqlite3_prepare_v2()] (and its variants) or [sqlite3_reset()] and
-** before [sqlite3_step()].
-** Bindings are not cleared by the [sqlite3_reset()] routine.
-** Unbound parameters are interpreted as NULL.
-**
-** These routines return [SQLITE_OK] on success or an error code if
-** anything goes wrong.  [SQLITE_RANGE] is returned if the parameter
-** index is out of range.  [SQLITE_NOMEM] is returned if malloc fails.
-** [SQLITE_MISUSE] might be returned if these routines are called on a
-** virtual machine that is the wrong state or which has already been finalized.
-** Detection of misuse is unreliable.  Applications should not depend
-** on SQLITE_MISUSE returns.  SQLITE_MISUSE is intended to indicate a
-** a logic error in the application.  Future versions of SQLite might
-** panic rather than return SQLITE_MISUSE.

-** The details of the behavior of this sqlite3_step() interface depend

-** interface [sqlite3_prepare()] and [sqlite3_prepare16()].  The use of the
-** new "v2" interface is recommended for new applications but the legacy
-** interface will continue to be supported.
-**
-** In the legacy interface, the return value will be either [SQLITE_BUSY], 
-** [SQLITE_DONE], [SQLITE_ROW], [SQLITE_ERROR], or [SQLITE_MISUSE].
-** With the "v2" interface, any of the other [SQLITE_OK | result code]
-** or [SQLITE_IOERR_READ | extended result code] might be returned as
-** well.
-**
-** [SQLITE_BUSY] means that the database engine was unable to acquire the
-** database locks it needs to do its job.  If the statement is a COMMIT
-** or occurs outside of an explicit transaction, then you can retry the
-** statement.  If the statement is not a COMMIT and occurs within a
-** explicit transaction then you should rollback the transaction before
-** continuing.
-**
-** [SQLITE_DONE] means that the statement has finished executing
-** successfully.  sqlite3_step() should not be called again on this virtual
-** machine without first calling [sqlite3_reset()] to reset the virtual
-** machine back to its initial state.
-**
-** If the SQL statement being executed returns any data, then 
-** [SQLITE_ROW] is returned each time a new row of data is ready
-** for processing by the caller. The values may be accessed using
-** the [sqlite3_column_int | column access functions].
-** sqlite3_step() is called again to retrieve the next row of data.
-** 
-** [SQLITE_ERROR] means that a run-time error (such as a constraint
-** violation) has occurred.  sqlite3_step() should not be called again on
-** the VM. More information may be found by calling [sqlite3_errmsg()].
-** With the legacy interface, a more specific error code (example:
-** [SQLITE_INTERRUPT], [SQLITE_SCHEMA], [SQLITE_CORRUPT], and so forth)
-** can be obtained by calling [sqlite3_reset()] on the
-** [prepared statement].  In the "v2" interface,
-** the more specific error code is returned directly by sqlite3_step().
-**
-** [SQLITE_MISUSE] means that the this routine was called inappropriately.
-** Perhaps it was called on a [prepared statement] that has
-** already been [sqlite3_finalize | finalized] or on one that had 
-** previously returned [SQLITE_ERROR] or [SQLITE_DONE].  Or it could
-** be the case that the same database connection is being used by two or

-** In the legacy interface, 
-** the sqlite3_step() API always returns a generic error code,
-** [SQLITE_ERROR], following any error other than [SQLITE_BUSY]
-** and [SQLITE_MISUSE].  You must call [sqlite3_reset()] or
-** [sqlite3_finalize()] in order to find one of the specific
-** [error codes] that better describes the error.
-** We admit that this is a goofy design.  The problem has been fixed
-** with the "v2" interface.  If you prepare all of your SQL statements
-** using either [sqlite3_prepare_v2()] or [sqlite3_prepare16_v2()] instead
-** of the legacy [sqlite3_prepare()] and [sqlite3_prepare16()], then the 
-** more specific [error codes] are returned directly

-** If the result is a numeric value then sqlite3_column_bytes() uses
-** [sqlite3_snprintf()] to convert that value to a UTF-8 string and returns
-** the number of bytes in that string.
-** The value returned does not include the zero terminator at the end
-** of the string.  For clarity: the value returned is the number of
-** bytes in the string, not the number of characters.
-**
-** Strings returned by sqlite3_column_text() and sqlite3_column_text16(),
-** even empty strings, are always zero terminated.  The return
-** value from sqlite3_column_blob() for a zero-length blob is an arbitrary
-** pointer, possibly even a NULL pointer.
-**
-** The sqlite3_column_bytes16() routine is similar to sqlite3_column_bytes()
-** but leaves the result in UTF-16 in native byte order instead of UTF-8.  
-** The zero terminator is not included in this count.
-**
-** The object returned by [sqlite3_column_value()] is an
-** [unprotected sqlite3_value] object.  An unprotected sqlite3_value object
-** may only be used with [sqlite3_bind_value()] and [sqlite3_result_value()].
-** If the [unprotected sqlite3_value] object returned by
-** [sqlite3_column_value()] is used in any other way, including calls
-** to routines like 
-** [sqlite3_value_int()], [sqlite3_value_text()], or [sqlite3_value_bytes()],
-** then the behavior is undefined.
-**
-** These routines attempt to convert the value where appropriate.  For
-** example, if the internal representation is FLOAT and a text result
-** is requested, [sqlite3_snprintf()] is used internally to do the conversion
-** automatically.  The following table details the conversions that
-** are applied:
-**
-** <blockquote>
-** <table border="1">
-** <tr><th> Internal<br>Type <th> Requested<br>Type <th>  Conversion
-**
-** <tr><td>  NULL    <td> INTEGER   <td> Result is 0
-** <tr><td>  NULL    <td>  FLOAT    <td> Result is 0.0
-** <tr><td>  NULL    <td>   TEXT    <td> Result is NULL pointer
-** <tr><td>  NULL    <td>   BLOB    <td> Result is NULL pointer
-** <tr><td> INTEGER  <td>  FLOAT    <td> Convert from integer to float
-** <tr><td> INTEGER  <td>   TEXT    <td> ASCII rendering of the integer
-** <tr><td> INTEGER  <td>   BLOB    <td> Same as for INTEGER->TEXT
-** <tr><td>  FLOAT   <td> INTEGER   <td> Convert from float to integer
-** <tr><td>  FLOAT   <td>   TEXT    <td> ASCII rendering of the float
-** <tr><td>  FLOAT   <td>   BLOB    <td> Same as FLOAT->TEXT
-** <tr><td>  TEXT    <td> INTEGER   <td> Use atoi()
-** <tr><td>  TEXT    <td>  FLOAT    <td> Use atof()
-** <tr><td>  TEXT    <td>   BLOB    <td> No change
-** <tr><td>  BLOB    <td> INTEGER   <td> Convert to TEXT then use atoi()
-** <tr><td>  BLOB    <td>  FLOAT    <td> Convert to TEXT then use atof()
-** <tr><td>  BLOB    <td>   TEXT    <td> Add a zero terminator if needed
-** </table>
-** </blockquote>
-**
-** The table above makes reference to standard C library functions atoi()
-** and atof().  SQLite does not really use these functions.  It has its
-** on equavalent internal routines.  The atoi() and atof() names are
-** used in the table for brevity and because they are familiar to most
-** C programmers.
-**
-** Note that when type conversions occur, pointers returned by prior
-** calls to sqlite3_column_blob(), sqlite3_column_text(), and/or
-** sqlite3_column_text16() may be invalidated. 
-** Type conversions and pointer invalidations might occur
-** in the following cases:
-**
-** <ul>
-** <li><p>  The initial content is a BLOB and sqlite3_column_text() 
-**          or sqlite3_column_text16() is called.  A zero-terminator might
-**          need to be added to the string.</p></li>
-**
-** <li><p>  The initial content is UTF-8 text and sqlite3_column_bytes16() or
-**          sqlite3_column_text16() is called.  The content must be converted
-**          to UTF-16.</p></li>
-**
-** <li><p>  The initial content is UTF-16 text and sqlite3_column_bytes() or
-**          sqlite3_column_text() is called.  The content must be converted
-**          to UTF-8.</p></li>
-** </ul>
-**
-** Conversions between UTF-16be and UTF-16le are always done in place and do
-** not invalidate a prior pointer, though of course the content of the buffer
-** that the prior pointer points to will have been modified.  Other kinds
-** of conversion are done in place when it is possible, but sometime it is
-** not possible and in those cases prior pointers are invalidated.  
-**
-** The safest and easiest to remember policy is to invoke these routines
-** in one of the following ways:
-**
-**  <ul>
-**  <li>sqlite3_column_text() followed by sqlite3_column_bytes()</li>
-**  <li>sqlite3_column_blob() followed by sqlite3_column_bytes()</li>
-**  <li>sqlite3_column_text16() followed by sqlite3_column_bytes16()</li>
-**  </ul>
-**
-** In other words, you should call sqlite3_column_text(), sqlite3_column_blob(),
-** or sqlite3_column_text16() first to force the result into the desired
-** format, then invoke sqlite3_column_bytes() or sqlite3_column_bytes16() to
-** find the size of the result.  Do not mix call to sqlite3_column_text() or
-** sqlite3_column_blob() with calls to sqlite3_column_bytes16().  And do not
-** mix calls to sqlite3_column_text16() with calls to sqlite3_column_bytes().
-**
-** The pointers returned are valid until a type conversion occurs as
-** described above, or until [sqlite3_step()] or [sqlite3_reset()] or
-** [sqlite3_finalize()] is called.  The memory space used to hold strings
-** and blobs is freed automatically.  Do <b>not</b> pass the pointers returned
-** [sqlite3_column_blob()], [sqlite3_column_text()], etc. into 
-** [sqlite3_free()].
-**
-** If a memory allocation error occurs during the evaluation of any
-** of these routines, a default value is returned.  The default value
-** is either the integer 0, the floating point number 0.0, or a NULL
-** pointer.  Subsequent calls to [sqlite3_errcode()] will return
-** [SQLITE_NOMEM].

-** CAPI3REF: Create Or Redefine SQL Functions {F16100}
-** KEYWORDS: {function creation routines} 
-**
-** These two functions (collectively known as
-** "function creation routines") are used to add SQL functions or aggregates
-** or to redefine the behavior of existing SQL functions or aggregates.  The
-** difference only between the two is that the second parameter, the
-** name of the (scalar) function or aggregate, is encoded in UTF-8 for
-** sqlite3_create_function() and UTF-16 for sqlite3_create_function16().
-**
-** The first parameter is the [database connection] to which the SQL
-** function is to be added.  If a single
-** program uses more than one [database connection] internally, then SQL
-** functions must be added individually to each [database connection].
-**
-** The second parameter is the name of the SQL function to be created
-** or redefined.
-** The length of the name is limited to 255 bytes, exclusive of the 
-** zero-terminator.  Note that the name length limit is in bytes, not
-** characters.  Any attempt to create a function with a longer name
-** will result in an SQLITE_ERROR error.
-**
-** The third parameter is the number of arguments that the SQL function or
-** aggregate takes. If this parameter is negative, then the SQL function or
-** aggregate may take any number of arguments.
-**
-** The fourth parameter, eTextRep, specifies what 
-** [SQLITE_UTF8 | text encoding] this SQL function prefers for
-** its parameters.  Any SQL function implementation should be able to work
-** work with UTF-8, UTF-16le, or UTF-16be.  But some implementations may be
-** more efficient with one encoding than another.  It is allowed to
-** invoke sqlite3_create_function() or sqlite3_create_function16() multiple
-** times with the same function but with different values of eTextRep.
-** When multiple implementations of the same function are available, SQLite
-** will pick the one that involves the least amount of data conversion.
-** If there is only a single implementation which does not care what
-** text encoding is used, then the fourth argument should be
-** [SQLITE_ANY].
-**
-** The fifth parameter is an arbitrary pointer.  The implementation
-** of the function can gain access to this pointer using
-** [sqlite3_user_data()].
-**
-** The seventh, eighth and ninth parameters, xFunc, xStep and xFinal, are
-** pointers to C-language functions that implement the SQL
-** function or aggregate. A scalar SQL function requires an implementation of
-** the xFunc callback only, NULL pointers should be passed as the xStep
-** and xFinal parameters. An aggregate SQL function requires an implementation
-** of xStep and xFinal and NULL should be passed for xFunc. To delete an
-** existing SQL function or aggregate, pass NULL for all three function
-** callback.
-**
-** It is permitted to register multiple implementations of the same
-** functions with the same name but with either differing numbers of
-** arguments or differing perferred text encodings.  SQLite will use

-**
-** The xFunc (for scalar functions) or xStep (for aggregates) parameters

-** define callbacks that implement the SQL functions and aggregates.
-** The 4th parameter to these callbacks is an array of pointers to
-** [protected sqlite3_value] objects.  There is one [sqlite3_value] object for
-** each parameter to the SQL function.  These routines are used to
-** extract values from the [sqlite3_value] objects.
-**
-** These routines work only with [protected sqlite3_value] objects.
-** Any attempt to use these routines on an [unprotected sqlite3_value]
-** object results in undefined behavior.
-**
-** These routines work just like the corresponding 
-** [sqlite3_column_blob | sqlite3_column_* routines] except that 
-** these routines take a single [protected sqlite3_value] object pointer
-** instead of an [sqlite3_stmt*] pointer and an integer column number.

-** in the native byte-order of the host machine.  The
-** sqlite3_value_text16be() and sqlite3_value_text16le() interfaces
-** extract UTF16 strings as big-endian and little-endian respectively.
-**
-** The sqlite3_value_numeric_type() interface attempts to apply
-** numeric affinity to the value.  This means that an attempt is
-** made to convert the value to an integer or floating point.  If
-** such a conversion is possible without loss of information (in other
-** words if the value is a string that looks like a number)
-** then the conversion is done.  Otherwise no conversion occurs.  The 
-** [SQLITE_INTEGER | datatype] after conversion is returned.
-**

-** [sqlite3_value_bytes()], [sqlite3_value_bytes16()], [sqlite3_value_text()],
-** or [sqlite3_value_text16()].

-** CAPI3REF: Setting The Result Of An SQL Function {F16400}
-**
-** These routines are used by the xFunc or xFinal callbacks that
-** implement SQL functions and aggregates.  See
-** [sqlite3_create_function()] and [sqlite3_create_function16()]
-** for additional information.
-**
-** These functions work very much like the 
-** [sqlite3_bind_blob | sqlite3_bind_*] family of functions used
-** to bind values to host parameters in prepared statements.
-** Refer to the
-** [sqlite3_bind_blob | sqlite3_bind_* documentation] for
-** additional information.
-**
-** The sqlite3_result_blob() interface sets the result from
-** an application defined function to be the BLOB whose content is pointed
-** to by the second parameter and which is N bytes long where N is the
-** third parameter. 
-** The sqlite3_result_zeroblob() inerfaces set the result of
-** the application defined function to be a BLOB containing all zero
-** bytes and N bytes in size, where N is the value of the 2nd parameter.
-**
-** The sqlite3_result_double() interface sets the result from
-** an application defined function to be a floating point value specified
-** by its 2nd argument.
-**
-** The sqlite3_result_error() and sqlite3_result_error16() functions
-** cause the implemented SQL function to throw an exception.
-** SQLite uses the string pointed to by the
-** 2nd parameter of sqlite3_result_error() or sqlite3_result_error16()
-** as the text of an error message.  SQLite interprets the error
-** message string from sqlite3_result_error() as UTF8. SQLite
-** interprets the string from sqlite3_result_error16() as UTF16 in native
-** byte order.  If the third parameter to sqlite3_result_error()
-** or sqlite3_result_error16() is negative then SQLite takes as the error
-** message all text up through the first zero character.
-** If the third parameter to sqlite3_result_error() or
-** sqlite3_result_error16() is non-negative then SQLite takes that many
-** bytes (not characters) from the 2nd parameter as the error message.
-** The sqlite3_result_error() and sqlite3_result_error16()
-** routines make a copy private copy of the error message text before
-** they return.  Hence, the calling function can deallocate or
-** modify the text after they return without harm.
-** The sqlite3_result_error_code() function changes the error code
-** returned by SQLite as a result of an error in a function.  By default,
-** the error code is SQLITE_ERROR.  A subsequent call to sqlite3_result_error()
-** or sqlite3_result_error16() resets the error code to SQLITE_ERROR.
-**
-** The sqlite3_result_toobig() interface causes SQLite
-** to throw an error indicating that a string or BLOB is to long
-** to represent.  The sqlite3_result_nomem() interface
-** causes SQLite to throw an exception indicating that the a
-** memory allocation failed.
-**
-** The sqlite3_result_int() interface sets the return value
-** of the application-defined function to be the 32-bit signed integer
-** value given in the 2nd argument.
-** The sqlite3_result_int64() interface sets the return value
-** of the application-defined function to be the 64-bit signed integer
-** value given in the 2nd argument.
-**
-** The sqlite3_result_null() interface sets the return value
-** of the application-defined function to be NULL.
-**
-** The sqlite3_result_text(), sqlite3_result_text16(), 
-** sqlite3_result_text16le(), and sqlite3_result_text16be() interfaces
-** set the return value of the application-defined function to be
-** a text string which is represented as UTF-8, UTF-16 native byte order,
-** UTF-16 little endian, or UTF-16 big endian, respectively.
-** SQLite takes the text result from the application from
-** the 2nd parameter of the sqlite3_result_text* interfaces.
-** If the 3rd parameter to the sqlite3_result_text* interfaces
-** is negative, then SQLite takes result text from the 2nd parameter 
-** through the first zero character.
-** If the 3rd parameter to the sqlite3_result_text* interfaces
-** is non-negative, then as many bytes (not characters) of the text
-** pointed to by the 2nd parameter are taken as the application-defined
-** function result.
-** If the 4th parameter to the sqlite3_result_text* interfaces
-** or sqlite3_result_blob is a non-NULL pointer, then SQLite calls that
-** function as the destructor on the text or blob result when it has
-** finished using that result.
-** If the 4th parameter to the sqlite3_result_text* interfaces
-** or sqlite3_result_blob is the special constant SQLITE_STATIC, then
-** SQLite assumes that the text or blob result is constant space and
-** does not copy the space or call a destructor when it has
-** finished using that result.
-** If the 4th parameter to the sqlite3_result_text* interfaces
-** or sqlite3_result_blob is the special constant SQLITE_TRANSIENT
-** then SQLite makes a copy of the result into space obtained from
-** from [sqlite3_malloc()] before it returns.
-**
-** The sqlite3_result_value() interface sets the result of
-** the application-defined function to be a copy the
-** [unprotected sqlite3_value] object specified by the 2nd parameter.  The
-** sqlite3_result_value() interface makes a copy of the [sqlite3_value]
-** so that [sqlite3_value] specified in the parameter may change or
-** be deallocated after sqlite3_result_value() returns without harm.
-** A [protected sqlite3_value] object may always be used where an

-** CAPI3REF: Define New Collating Sequences {F16600}
-**
-** These functions are used to add new collation sequences to the
-** [sqlite3*] handle specified as the first argument. 
-**
-** The name of the new collation sequence is specified as a UTF-8 string
-** for sqlite3_create_collation() and sqlite3_create_collation_v2()
-** and a UTF-16 string for sqlite3_create_collation16(). In all cases
-** the name is passed as the second function argument.
-**
-** The third argument may be one of the constants [SQLITE_UTF8],
-** [SQLITE_UTF16LE] or [SQLITE_UTF16BE], indicating that the user-supplied
-** routine expects to be passed pointers to strings encoded using UTF-8,
-** UTF-16 little-endian or UTF-16 big-endian respectively. The
-** third argument might also be [SQLITE_UTF16_ALIGNED] to indicate that
-** the routine expects pointers to 16-bit word aligned strings
-** of UTF16 in the native byte order of the host computer.
-**
-** A pointer to the user supplied routine must be passed as the fifth
-** argument.  If it is NULL, this is the same as deleting the collation
-** sequence (so that SQLite cannot call it anymore).
-** Each time the application
-** supplied function is invoked, it is passed a copy of the void* passed as
-** the fourth argument to sqlite3_create_collation() or
-** sqlite3_create_collation16() as its first parameter.
-**
-** The remaining arguments to the application-supplied routine are two strings,
-** each represented by a (length, data) pair and encoded in the encoding
-** that was passed as the third argument when the collation sequence was
-** registered. {END} The application defined collation routine should
-** return negative, zero or positive if
-** the first string is less than, equal to, or greater than the second
-** string. i.e. (STRING1 - STRING2).
-**
-** The sqlite3_create_collation_v2() works like sqlite3_create_collation()
-** excapt that it takes an extra argument which is a destructor for
-** the collation.  The destructor is called when the collation is
-** destroyed and is passed a copy of the fourth parameter void* pointer
-** of the sqlite3_create_collation_v2().
-** Collations are destroyed when
-** they are overridden by later calls to the collation creation functions
-** or when the [sqlite3*] database handle is closed using [sqlite3_close()].

-**          implement collation X on [database connection] B for

-** {F16606} Successive calls to [sqlite3_create_collation_v2(B,X,E,P,F,D)]

-**          is passed through as the first parameter to the comparison

-**
-** {F16621} A call to [sqlite3_create_collation(B,X,E,P,F)] is exactly
-**          the same as a call to [sqlite3_create_collation_v2()] with
-**          the same parameters and a NULL destructor.
-**
-** {F16624} Following a [sqlite3_create_collation_v2(B,X,E,P,F,D)],
-**          SQLite uses the comparison function F for all text comparison
-**          operations on [database connection] B on text values that
-**          use the collating sequence name X.
-**
-** {F16627} The [sqlite3_create_collation16(B,X,E,P,F)] works the same
-**          as [sqlite3_create_collation(B,X,E,P,F)] except that the
-**          collation name X is understood as UTF-16 in native byte order
-**          instead of UTF-8.
-**
-** {F16630} When multiple comparison functions are available for the same

-** table accessible using the connection handle passed as the first function 
-** argument.
-**
-** The column is identified by the second, third and fourth parameters to 
-** this function. The second parameter is either the name of the database
-** (i.e. "main", "temp" or an attached database) containing the specified
-** table or NULL. If it is NULL, then all attached databases are searched
-** for the table using the same algorithm as the database engine uses to 
-** resolve unqualified table references.
-**
-** The third and fourth parameters to this function are the table and column 
-** name of the desired column, respectively. Neither of these parameters 
-** may be NULL.
-**
-** Meta information is returned by writing to the memory locations passed as
-** the 5th and subsequent parameters to this function. Any of these 
-** arguments may be NULL, in which case the corresponding element of meta 
-** information is ommitted.

-** pass information into and receive the reply from the xBestIndex
-** method of an sqlite3_module.  The fields under **Inputs** are the
-** inputs to xBestIndex and are read-only.  xBestIndex inserts its
-** results into the **Outputs** fields.
-**
-** The aConstraint[] array records WHERE clause constraints of the
-** form:
-**
-**         column OP expr
-**
-** Where OP is =, &lt;, &lt;=, &gt;, or &gt;=.  
-** The particular operator is stored
-** in aConstraint[].op.  The index of the column is stored in 
-** aConstraint[].iColumn.  aConstraint[].usable is TRUE if the
-** expr on the right-hand side can be evaluated (and thus the constraint
-** is usable) and false if it cannot.
-**
-** The optimizer automatically inverts terms of the form "expr OP column"
-** and makes other simplifications to the WHERE clause in an attempt to
-** get as many WHERE clause terms into the form shown above as possible.
-** The aConstraint[] array only reports WHERE clause terms in the correct
-** form that refer to the particular virtual table being queried.
-**
-** Information about the ORDER BY clause is stored in aOrderBy[].
-** Each term of aOrderBy records a column of the ORDER BY clause.
-**
-** The xBestIndex method must fill aConstraintUsage[] with information
-** about what parameters to pass to xFilter.  If argvIndex>0 then
-** the right-hand side of the corresponding aConstraint[] is evaluated
-** and becomes the argvIndex-th entry in argv.  If aConstraintUsage[].omit
-** is true, then the constraint is assumed to be fully handled by the
-** virtual table and is not checked again by SQLite.
-**
-** The idxNum and idxPtr values are recorded and passed into xFilter.
-** sqlite3_free() is used to free idxPtr if needToFreeIdxPtr is true.

-** The same VFS can be registered multiple times without injury.
-** To make an existing VFS into the default VFS, register it again

-** then the behavior is undefined.

-** CAPI3REF: Mutexes {F17000}
-**
-** The SQLite core uses these routines for thread
-** synchronization.  Though they are intended for internal
-** use by SQLite, code that links against SQLite is
-** permitted to use any of these routines.
-**
-** The SQLite source code contains multiple implementations 
-** of these mutex routines.  An appropriate implementation
-** is selected automatically at compile-time.  The following
-** implementations are available in the SQLite core:
-**
-** <ul>
-** <li>   SQLITE_MUTEX_OS2
-** <li>   SQLITE_MUTEX_PTHREAD
-** <li>   SQLITE_MUTEX_W32
-** <li>   SQLITE_MUTEX_NOOP
-** </ul>
-**
-** The SQLITE_MUTEX_NOOP implementation is a set of routines 
-** that does no real locking and is appropriate for use in 
-** a single-threaded application.  The SQLITE_MUTEX_OS2,
-** SQLITE_MUTEX_PTHREAD, and SQLITE_MUTEX_W32 implementations
-** are appropriate for use on os/2, unix, and windows.
-** 
-** If SQLite is compiled with the SQLITE_MUTEX_APPDEF preprocessor
-** macro defined (with "-DSQLITE_MUTEX_APPDEF=1"), then no mutex
-** implementation is included with the library.  The
-** mutex interface routines defined here become external
-** references in the SQLite library for which implementations
-** must be provided by the application.  This facility allows an
-** application that links against SQLite to provide its own mutex
-** implementation without having to modify the SQLite core.
-**
-** {F17011} The sqlite3_mutex_alloc() routine allocates a new
-** mutex and returns a pointer to it. {F17012} If it returns NULL
-** that means that a mutex could not be allocated. {F17013} SQLite
-** will unwind its stack and return an error. {F17014} The argument
-** to sqlite3_mutex_alloc() is one of these integer constants:
-**
-** <ul>
-** <li>  SQLITE_MUTEX_FAST
-** <li>  SQLITE_MUTEX_RECURSIVE
-** <li>  SQLITE_MUTEX_STATIC_MASTER
-** <li>  SQLITE_MUTEX_STATIC_MEM
-** <li>  SQLITE_MUTEX_STATIC_MEM2
-** <li>  SQLITE_MUTEX_STATIC_PRNG
-** <li>  SQLITE_MUTEX_STATIC_LRU
-** <li>  SQLITE_MUTEX_STATIC_LRU2
-** </ul> {END}
-**
-** {F17015} The first two constants cause sqlite3_mutex_alloc() to create
-** a new mutex.  The new mutex is recursive when SQLITE_MUTEX_RECURSIVE
-** is used but not necessarily so when SQLITE_MUTEX_FAST is used. {END}
-** The mutex implementation does not need to make a distinction
-** between SQLITE_MUTEX_RECURSIVE and SQLITE_MUTEX_FAST if it does
-** not want to.  {F17016} But SQLite will only request a recursive mutex in
-** cases where it really needs one.  {END} If a faster non-recursive mutex
-** implementation is available on the host platform, the mutex subsystem
-** might return such a mutex in response to SQLITE_MUTEX_FAST.
-**
-** {F17017} The other allowed parameters to sqlite3_mutex_alloc() each return
-** a pointer to a static preexisting mutex. {END}  Four static mutexes are
-** used by the current version of SQLite.  Future versions of SQLite
-** may add additional static mutexes.  Static mutexes are for internal
-** use by SQLite only.  Applications that use SQLite mutexes should
-** use only the dynamic mutexes returned by SQLITE_MUTEX_FAST or
-** SQLITE_MUTEX_RECURSIVE.
-**
-** {F17018} Note that if one of the dynamic mutex parameters (SQLITE_MUTEX_FAST
-** or SQLITE_MUTEX_RECURSIVE) is used then sqlite3_mutex_alloc()
-** returns a different mutex on every call.  {F17034} But for the static 
-** mutex types, the same mutex is returned on every call that has
-** the same type number. {END}
-**
-** {F17019} The sqlite3_mutex_free() routine deallocates a previously
-** allocated dynamic mutex. {F17020} SQLite is careful to deallocate every
-** dynamic mutex that it allocates. {U17021} The dynamic mutexes must not be in 
-** use when they are deallocated. {U17022} Attempting to deallocate a static
-** mutex results in undefined behavior. {F17023} SQLite never deallocates
-** a static mutex. {END}
-**
-** The sqlite3_mutex_enter() and sqlite3_mutex_try() routines attempt
-** to enter a mutex. {F17024} If another thread is already within the mutex,
-** sqlite3_mutex_enter() will block and sqlite3_mutex_try() will return
-** SQLITE_BUSY. {F17025}  The sqlite3_mutex_try() interface returns SQLITE_OK
-** upon successful entry.  {F17026} Mutexes created using
-** SQLITE_MUTEX_RECURSIVE can be entered multiple times by the same thread.
-** {F17027} In such cases the,
-** mutex must be exited an equal number of times before another thread
-** can enter.  {U17028} If the same thread tries to enter any other
-** kind of mutex more than once, the behavior is undefined.
-** {F17029} SQLite will never exhibit
-** such behavior in its own use of mutexes. {END}
-**
-** Some systems (ex: windows95) do not the operation implemented by
-** sqlite3_mutex_try().  On those systems, sqlite3_mutex_try() will
-** always return SQLITE_BUSY.  {F17030} The SQLite core only ever uses
-** sqlite3_mutex_try() as an optimization so this is acceptable behavior. {END}
-**
-** {F17031} The sqlite3_mutex_leave() routine exits a mutex that was
-** previously entered by the same thread.  {U17032} The behavior
-** is undefined if the mutex is not currently entered by the
-** calling thread or is not currently allocated.  {F17033} SQLite will
-** never do either. {END}

-** The "printf" code that follows dates from the 1980's.  It is in
-** the public domain.  The original comments are included here for
-** completeness.  They are very out-of-date but might be useful as
-** an historical reference.  Most of the "enhancements" have been backed
-** out so that the functionality is now the same as standard printf().
-**
-**************************************************************************
-**
-** The following modules is an enhanced replacement for the "printf" subroutines
-** found in the standard C library.  The following enhancements are
-** supported:
-**
-**      +  Additional functions.  The standard set of "printf" functions
-**         includes printf, fprintf, sprintf, vprintf, vfprintf, and
-**         vsprintf.  This module adds the following:
-**
-**           *  snprintf -- Works like sprintf, but has an extra argument
-**                          which is the size of the buffer written to.
-**
-**           *  mprintf --  Similar to sprintf.  Writes output to memory
-**                          obtained from malloc.
-**
-**           *  xprintf --  Calls a function to dispose of output.
-**
-**           *  nprintf --  No output, but returns the number of characters
-**                          that would have been output by printf.
-**
-**           *  A v- version (ex: vsnprintf) of every function is also
-**              supplied.
-**
-**      +  A few extensions to the formatting notation are supported:
-**
-**           *  The "=" flag (similar to "-") causes the output to be
-**              be centered in the appropriately sized field.
-**
-**           *  The %b field outputs an integer in binary notation.
-**
-**           *  The %c field now accepts a precision.  The character output
-**              is repeated by the number of times the precision specifies.
-**
-**           *  The %' field works like %c, but takes as its character the
-**              next character of the format string, instead of the next
-**              argument.  For example,  printf("%.78'-")  prints 78 minus
-**              signs, the same as  printf("%.78c",'-').
-**
-**      +  When compiled using GCC on a SPARC, this version of printf is
-**         faster than the library printf for SUN OS 4.1.
-**
-**      +  All functions are fully reentrant.

-** The root program.  All variations call this core.

-** INPUTS:
-**   func   This is a pointer to a function taking three arguments
-**            1. A pointer to anything.  Same as the "arg" parameter.
-**            2. A pointer to the list of characters to be output
-**               (Note, this list is NOT null terminated.)
-**            3. An integer number of characters to be output.
-**               (Note: This number might be zero.)
-**
-**   arg    This is the pointer to anything which will be passed as the
-**          first argument to "func".  Use it for whatever you like.
-**
-**   fmt    This is the format string, as in the usual print.
-**
-**   ap     This is a pointer to a list of arguments.  Same as in
-**          vfprint.
-**
-** OUTPUTS:
-**          The return value is the total number of characters sent to
-**          the function "func".  Returns -1 on a error.
-**
-** Note that the order in which automatic variables are declared below
-** seems to make a big difference in determining how fast this beast
-** will run.
