|
|
*Purpose:

*
|
|
*Revision History:
|
|
* 09-09-91 ETC Created from stricmp.c.
|
|
* 12-09-91 ETC Use C for neutral locale.
|
|
* 04-07-92 KRS Updated and ripped out _INTL switches.
|
|
* 08-19-92 KRS Actived use of CompareStringW.
|
|
* 08-22-92 SRW Allow INTL definition to be conditional for building ntcrt.lib
|
|
* 09-02-92 SRW Get _INTL definition via ..\crt32.def
|
|
* 12-15-92 KRS Added robustness to non-_INTL code. Optimize.
|
|
* 04-06-93 SKS Replace _CRTAPI* with __cdecl
|
|
* 04-14-93 CFW Remove locale-sensitive portion.
|
|

|
|
* 10-25-94 GJF Now works in non-C locales.
|
|
* 09-26-95 GJF New locking macro, and scheme, for functions which
|
|
* reference the locale.
|
|
* 10-11-95 BWT Fix NTSUBSET

*Purpose:
|
|
* _wcsicmp perform a case-insensitive wchar_t string comparision.
|
|
* _wcsicmp is independent of locale.

*Entry:

*Return:

|
|
* >0 if dst > src
|
