WCSCOLL(3)                              BSD Library Functions Manual                              WCSCOLL(3)

NAME
     wcscoll, wcscoll_l -- compare wide strings according to current collation

LIBRARY
     Standard C Library (libc, -lc)

SYNOPSIS
     #include <wchar.h>

     int
     wcscoll(const wchar_t *ws1, const wchar_t *ws2);

     #include <wchar.h>
     #include <xlocale.h>

     int
     wcscoll_l(const wchar_t *ws1, const wchar_t *ws2, locale_t loc);

DESCRIPTION
     The wcscoll() function compares the null-terminated strings ws1 and ws2, according to the current
     locale's collation order.  In the ``C'' locale, wcscoll() is equivalent to wcscmp().

     Although the wcscoll() function uses the current locale, the wcscoll_l() function may be passed a
     locale directly. See xlocale(3) for more information.

RETURN VALUES
     The wcscoll() function returns an integer greater than, equal to, or less than 0, if ws1 is greater
     than, equal to, or less than ws2.

     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), xlocale(3)

STANDARDS
     The wcscoll() function conforms to ISO/IEC 9899:1999 (``ISO C99'').

BUGS
     The current implementation of wcscoll() only works in single-byte LC_CTYPE locales, and falls back to
     using wcscmp() in locales with extended character sets.
