+*sscanf.c - read formatted data from string
+*
+*	Copyright (c) 1985-1991, Microsoft Corporation. All rights reserved.
+*
+*Purpose:
+*	defines scanf() - reads formatted data from 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.
+*	12-11-87  JCR	Added "_LOAD_DS" to declaration
+*	06-13-88  JCR	Fake _iob entry is now static so that other routines can
+*			assume _iob entries are in DGROUP.
+*	06-06-89  JCR	386 mthread support -- threads share one locked iob.
+*	08-18-89  GJF	Clean up, now specific to OS/2 2.0 (i.e., 386 flat
+*			model). Also fixed indents.
+*	02-16-90  GJF	Fixed copyright
+*	03-19-90  GJF	Made calling type _CALLTYPE2, added #include
+*			<cruntime.h> and removed #include <register.h>.
+*	03-26-90  GJF	Added #include <string.h>.
+*	07-23-90  SBM	Replaced <assertm.h> by <assert.h>
+*	10-03-90  GJF	New-style function declarator.
+*       02-18-93  SRW   Make FILE a local and remove lock usage.

+*int sscanf(string, format, ...) - read formatted data from string
+*
+*Purpose:
+*	Reads formatted data from string into arguments.  _input does the real
+*	work here.  Sets up a FILE so file i/o operations can be used, makes
+*	string look like a huge buffer to it, but _filbuf will refuse to refill
+*	it if it is exhausted.
+*
+*	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.
+*
+*	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 staticly allocated 'fake' iob, we must
+*	lock/unlock to prevent collisions.
+*
+*Entry:
+*	char *string - string to read data from
+*	char *format - format string
+*	followed by list of pointers to storage for the data read.  The number
+*	and type are controlled by the format string.
+*
+*Exit:
+*	returns number of fields read and assigned
+*
+*Exceptions:
