NAME    [Toc]    [Back]

     wcscoll -- compare wide strings according to current collation

LIBRARY    [Toc]    [Back]

     Standard C Library (libc, -lc)

SYNOPSIS    [Toc]    [Back]

     #include <wchar.h>

     int
     wcscoll(const wchar_t *s1, const wchar_t *s2);

DESCRIPTION    [Toc]    [Back]

     The wcscoll() function compares the null-terminated strings s1 and s2
     according to the current locale collation order.  In the ``C'' locale,
     wcscoll() is equivalent to wcscmp().

RETURN VALUES    [Toc]    [Back]

     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    [Toc]    [Back]

     The wcscoll() function will fail if:

     [EILSEQ]		An invalid wide character code was specified.

     [ENOMEM]		Cannot allocate enough memory for temporary buffers.

SEE ALSO    [Toc]    [Back]

     setlocale(3), strcoll(3), wcscmp(3), wcsxfrm(3)

STANDARDS    [Toc]    [Back]

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

BUGS    [Toc]    [Back]

     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.
