*printf.h - print formatted
|
|
*
|
|
* Copyright (c) 1985-1991, Microsoft Corporation. All rights reserved.
|
|
*
|
|
*Purpose:
|
|
* defines w4*printf() - print formatted data
|
|
* defines w4v*printf() - print formatted output, get data from an
|
|
* argument ptr instead of explicit args.
|
|
*
|
|
*Revision History:
|
|
* 09-02-83 RN original sprintf
|
|
* 06-17-85 TC rewrote to use new varargs macros, and to be vsprintf
|
|
* 04-13-87 JCR added const to declaration
|
|
* 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

* Prints formatted data, but gets data from an argument pointer.

* Sets up a w4io so file i/o operations can be used, make string look

* 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.
