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.
