-*vswprint.c - print formatted data into a string from var arg list
-*
-*Purpose:
-* defines vswprintf(), _vswprintf_c and _vsnwprintf() - print formatted output to
-* a string, get the data from an argument ptr instead of explicit
-* arguments.

-*
-*Purpose:
-* Prints formatted data, but to a string and gets data from an argument
-* pointer.
-* Sets up a FILE so file i/o operations can be used, make string look
-* like a huge buffer to it, but _flsbuf will refuse to flush it if it
-* fills up. Appends '\0' to make it a true string.
-*
-* Allocate the 'fake' _iob[] entryit statically instead of on
-* the stack so that other routines can assume that _iob[] entries are in
-* are in DGROUP and, thus, are near.
-*
-*ifdef _COUNT_
-*ifndef _SWPRINTFS_ERROR_RETURN_FIX
-* The _vsnwprintf() flavor takes a count argument that is
-* the max number of bytes that should be written to the
-* user's buffer.
-* We don't expose this function directly in the headers.
-*else
-* The _vswprintf_c() flavor does the same thing as the _snwprintf
-* above, but, it also fixes an issue in the return value in the case
-* when there isn't enough space to write the null terminator
-* We don't fix this issue in _vsnwprintf because of backward
-* compatibility. In new code, however, _vsnwprintf is #defined to
-* _vswprintf_c so users get the fix.
-*
-*endif
-*
-* Multi-thread: (1) Since there is no stream, this routine must never try
-* to get the stream lock (i.e., there is no stream lock either). (2)
-* Also, since there is only one statically allocated 'fake' iob, we must
-* lock/unlock to prevent collisions.
-*
-*Entry:
-* wchar_t *string - place to put destination string
-*ifdef _COUNT_
-* size_t count - max number of bytes to put in buffer
-*endif
-* wchar_t *format - format string, describes format of data
-* va_list ap - varargs argument pointer
-*
-*Exit:
-* returns number of wide characters in string
-* returns -2 if the string has been truncated (only in _vsnprintf_helper)
-* returns -1 in other error cases
