* Copyright (c) 1989-2001, Microsoft Corporation. All rights reserved.
|
|
*
|
|
*Purpose:
|
|
* Defines feof() (test for end-of-file on a stream) and ferror() (test
|
|
* for error on a stream).
|
|
*
|
|
*Revision History:
|
|
* 03-13-89 GJF Module created
|
|
* 03-27-89 GJF Moved to 386 tree
|
|
* 02-15-90 GJF Fixed copyright
|
|
* 03-16-90 GJF Made calling type _CALLTYPE1 and added #include
|
|
* <cruntime.h>.
|
|
* 10-02-90 GJF New-style function declarators.
|
|
* 04-06-93 SKS Replace _CRTAPI* with __cdecl
