*stricoll.c - Collate locale strings without regard to case
|
|
*
|
|
* Copyright (c) 1988-1995, Microsoft Corporation. All rights reserved.
|
|
*
|
|
*Purpose:
|
|
* Compare two strings using the locale LC_COLLATE information.
|
|
*
|
|
*Revision History:
|
|
* 10-16-91 ETC Created from strcoll.c
|
|
* 12-08-91 ETC Remove availability under !_INTL; updated api; add mt.
|
|
* 04-06-92 KRS Make work without _INTL switches too.
|
|
* 08-19-92 KRS Activate NLS support.
|
|
* 09-02-92 SRW Get _INTL definition via ..\crt32.def
|
|
* 12-16-92 KRS Optimize for CompareStringW by using -1 for string len.
|
|
* 04-06-93 SKS Replace _CRTAPI* with __cdecl
|
|
* 04-14-93 CFW Error sets errno, cleanup.
|
|
* 06-02-93 SRW ignore _INTL if _NTSUBSET_ defined.
|
|
* 09-15-93 CFW Use ANSI conformant "__" names.
|
|
* 09-22-93 CFW Use __crtxxx internal NLS API wrapper.
|
|
* 09-29-93 GJF Merged NT SDK and Cuda versions.
|
|
* 11-09-93 CFW Use LC_COLLATE code page for __crtxxx() conversion.
|
|
* 04-11-93 CFW Change NLSCMPERROR to _NLCMPERROR.
|
|
* 09-06-94 CFW Remove _INTL switch.
|
|
* 10-24-94 GJF Sped up C locale, multi-thread case.
|
|
* 12-29-94 CFW Merge non-Win32.
|
|
* 09-26-95 GJF New locking macro, and scheme, for functions which
|
|
* reference the locale.
|
|
* 10-30-95 GJF Specify SORT_STRINGSORT to CompareString.
|
|
* 11-25-95 BWT stricmp simply calls strcmpi... Use strcmpi instead.
