WCSCOLL(3) FreeBSD 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 null-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() only works in single-byte
LC_CTYPE locales, and falls back to using wcscmp() in locales with
extended character sets.
