|
*charmax.c - definition of _charmax variable
|
||
|
|
*
|
||
|
|
* Copyright (c) 1993-2001, Microsoft Corporation. All rights reserved.
|
||
|
|
*
|
||
|
|
*Purpose:
|
||
|
|
* defines _charmax
|
||
|
|
*
|
||
|
|
* According to ANSI, certain elements of the lconv structure must be
|
||
|
|
* initialized to CHAR_MAX and the value of CHAR_MAX changes when
|
||
|
|
* the user compiles -J. To reflect this change in the lconv structure,
|
||
|
|
* we initialize the structure to SCHAR_MAX, and when any of the users
|
||
|
|
* modules are compiled -J, the structure is updated.
|
||
|
|
*
|
||
|
|
* Note that this is not done for DLLs linked to the CRT DLL, because
|
||
|
|
* we do not want such DLLs to override the -J setting for an EXE
|
||
|
|
* linked to the CRT DLL. See comments in crtexe.c.
|
||
|
|
*
|
||
|
|
* Files involved:
|
||
|
|
*
|
||
|
|
* locale.h - if -J, generates an unresolved external to _charmax
|
||
|
|
* charmax.c - defines _charmax and sets to UCHAR_MAX (255), places
|
||
|
|
* _lconv_init in startup initializer table if pulled in by -J
|
||
|
|
* lconv.c - initializes lconv structure to SCHAR_MAX (127),
|
||
|
|
* since libraries built without -J
|
||
|
|
* lcnvinit.c - sets lconv members to 25.
|
||
|
|
**
|
||
|
|
*Revision History:
|
||
|
|
* 04-06-93 CFW Module created.
|
||
|
|
* 04-14-93 CFW Change _charmax from short to int, cleanup.
|
||
|
|
* 09-15-93 SKS Use ANSI conformant "__" names.
|
||
|
|
* 11-01-93 GJF Cleaned up a bit.
|
||
|
|
* 04-28-99 PML Wrap __declspec(allocate()) in _CRTALLOC macro.
|
||
|
|
* 03-27-01 PML .CRT$XI routines must now return 0 or _RT_* fatal
|
||
|
|
* error code (vs7#231220)
