WCSCOLL(3) Library Functions Manual WCSCOLL(3) NAME wcscoll - compare wide strings according to current collation LIBRARY Standard C Library (libc, -lc) SYNOPSIS #include <wchar.h> int wcscoll(const wchar_t *s1, const wchar_t *s2); DESCRIPTION The wcscoll() function compares the nul-terminated strings s1 and s2 according to the current locale collation order. In the "C" locale, wcscoll() is equivalent to wcscmp(). RETURN VALUES The wcscoll() function returns an integer greater than, equal to, or less than 0, if s1 is greater than, equal to, or less than s2. No return value is reserved to indicate errors; callers should set errno to 0 before calling wcscoll(). If it is non-zero upon return from wcscoll(), an error has occurred. ERRORS The wcscoll() function will fail if: [EILSEQ] An invalid wide-character code was specified. [ENOMEM] Cannot allocate enough memory for temporary buffers. SEE ALSO setlocale(3), strcoll(3), wcscmp(3), wcsxfrm(3) STANDARDS The wcscoll() function conforms to ISO/IEC 9899:1999 ("ISO C99"). BUGS The current implementation of wcscoll() function disregards LC_COLLATE locales, and falls back to using the wcscmp() function. NetBSD 8.0 October 13, 2006 NetBSD 8.0
