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.
