+*sprintf.c - print formatted to string
+*
+*	Copyright (c) 1985-1991, Microsoft Corporation. All rights reserved.
+*
+*Purpose:
+*	defines sprintf() and _snprintf() - print formatted data to string
+*
+*Revision History:
+*	09-02-83  RN	initial version
+*	04-13-87  JCR	added const to declaration
+*	06-24-87  JCR	(1) Made declaration conform to ANSI prototype and use
+*			the va_ macros; (2) removed SS_NE_DS conditionals.
+*	11-07-87  JCR	Multi-thread support
+*	12-11-87  JCR	Added "_LOAD_DS" to declaration
+*	05-27-88  PHG	Merged DLL and normal versions
+*	06-13-88  JCR	Fake _iob entry is now static so that other routines
+*			can assume _iob entries are in DGROUP.
+*	08-25-88  GJF	Define MAXSTR to be INT_MAX (from LIMITS.H).
+*	06-06-89  JCR	386 mthread support
+*	08-18-89  GJF	Clean up, now specific to OS/2 2.0 (i.e., 386 flat
+*			model). Also fixed copyright and indents.
+*	02-16-90  GJF	Fixed copyright
+*	03-19-90  GJF	Made calling type _CALLTYPE2, added #include
+*			<cruntime.h> and removed #include <register.h>.
+*	07-23-90  SBM	Replaced <assertm.h> by <assert.h>
+*	10-03-90  GJF	New-style function declarator.
+*	09-24-91  JCR	Added _snprintf()

+#ifndef _COUNT_
+*int sprintf(string, format, ...) - print formatted data to string
+#else
+*int _snprintf(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() 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:
