wcscasecmp - Man Page

Standard C library (libc, -lc)

#include <wchar.h>

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

wcscasecmp():

    Since glibc 2.10:
        _POSIX_C_SOURCE >= 200809L
    Before glibc 2.10:
        _GNU_SOURCE

The wcscasecmp() function is the wide-character equivalent of the strcasecmp(3) function. It compares the wide-character string pointed to by s1 and the wide-character string pointed to by s2, ignoring case differences (towupper(3), towlower(3)).

The wcscasecmp() function returns zero if the wide-character strings at s1 and s2 are equal except for case distinctions. It returns a positive integer if s1 is greater than s2, ignoring case. It returns a negative integer if s1 is smaller than s2, ignoring case.

For an explanation of the terms used in this section, see attributes(7).

POSIX.1-2008.

glibc 2.1.

The behavior of wcscasecmp() depends on the LC_CTYPE category of the current locale.
