*stricoll.c - Collate locale strings without regard to case

|
|
* Copyright (c) 1988-1993, 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.
|
|
* 06-02-93 SRW ignore _INTL if _NTSUBSET_ defined.
