NAME

wcscoll, wcscoll_l — compare wide strings according to the current collation

SYNOPSIS

#include <wchar.h>

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

int
wcscoll_l(const wchar_t *s1, const wchar_t *s2, locale_t locale);

DESCRIPTION

The wcscoll() and wcscoll_l() functions lexicographically compare the NUL-terminated wide strings s1 and s2 according to the current locale collation and return an integer greater than, equal to, or less than 0, according to whether s1 is greater than, equal to, or less than s2.

On OpenBSD, they have the same effect as wcscmp(3), and the global locale, the thread-specific locale, and the locale argument are ignored. On other operating systems, the results may depend on the LC_CTYPE and LC_COLLATE locale categories set with setlocale(3), uselocale(3), or newlocale(3).

SEE ALSO

newlocale(3), setlocale(3), wcscmp(3), wcsxfrm(3)

STANDARDS

The wcscoll() function conforms to ISO/IEC 9899:1999 (“ISO C99”), and wcscoll_l() to IEEE Std 1003.1-2008 (“POSIX.1”).

HISTORY

The wcscoll() function has been available since OpenBSD 4.8, and wcscoll_l() since OpenBSD 6.2.
