wcscasecmp(3)

NAME#

wcscasecmp - compare two wide-character strings, ignoring case

LIBRARY#

Standard C library (libc, -lc)

SYNOPSIS#

#include <wchar.h>

int wcscasecmp(const wchar_t *\ns1\n, const wchar_t *\ns2\n);

wcscasecmp():

\n
    Since glibc 2.10:

\n
    Before glibc 2.10:
\n
        _GNU_SOURCE

DESCRIPTION#

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)).

RETURN VALUE#

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.

ATTRIBUTES#

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