+*ifndef _COUNT_
+*int sprintf_s(string, format, ...) - print formatted data to string
+*else
+*int _snprintf_s(string, cnt, format, ...) - print formatted data to string
+*endif
+*
+*Purpose:
+*       Prints formatted data to the using the format string to
+*       format data and getting as many arguments as called for
+*       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. _output does the real work here
+*
+*       Allocate the 'fake' _iob[] entry 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_
+*       The _snprintf_s() flavor takes a count argument that is
+*       the max number of bytes that should be written to the
+*       user's buffer.
+*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:
+*       char *string - pointer to place to put output
+*ifdef _COUNT_
+*       size_t count - max number of bytes to put in buffer
+*endif
+*       char *format - format string to control data format/number
+*       of arguments followed by list of arguments, number and type
+*       controlled by format string
+*
+*Exit:
+*       returns number of characters printed
+*
+*Exceptions:
