|
|
*Purpose:
|
|
* Compare two wchar_t strings using the locale LC_COLLATE information.
|
|
*
|
|
*Revision History:
|
|
* 09-09-91 ETC Created from strcoll.c.
|
|
* 04-06-92 KRS Make work without _INTL also.
|
|
* 08-19-92 KRS Activate NLS support.
|
|
* 09-02-92 SRW Get _INTL definition via ..\crt32.def
|
|
* 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.
|
|
* 02-07-94 CFW POSIXify.
|
|
* 04-11-93 CFW Change NLSCMPERROR to _NLCMPERROR.
|
|
* 09-06-94 CFW Remove _INTL switch.
|
|
* 10-25-94 GJF Sped up C locale, multi-thread case.
|
|
* 09-26-95 GJF New locking macro, and scheme, for functions which
|
|
* reference the locale.
|
|
* 10-30-95 GJF Specify SORT_STRINGSORT to CompareString.
|
|
* 07-16-96 SKS Added missing call to _unlock_locale()
|
|
* 11-24-97 GJF Removed bogus codepage determination.
|
|
* 01-12-98 GJF Use _lc_collate_cp codepage.
|
|

*int wcscoll() - Collate wide-character locale strings
|
|
*
|
|
*Purpose:
|
|
* Compare two wchar_t strings using the locale LC_COLLATE information.
|
|
* In the C locale, wcscmp() is used to make the comparison.
|
|
*
|
|
*Entry:
|
|
* const wchar_t *s1 = pointer to the first string
|
|
* const wchar_t *s2 = pointer to the second string
|
|
*
|
|
*Exit:
|
|
* -1 = first string less than second string
|
|
* 0 = strings are equal
|
|
* 1 = first string greater than second string
|
|
* This range of return values may differ from other *cmp/*coll functions.
|
|
*
|
|
*Exceptions:
|
|
* _NLSCMPERROR = error
|
|
* errno = EINVAL
|
