wcscasecmp - compare two wide-character strings, ignoring case
#include <wchar.h>
int wcscasecmp(const wchar_t *s1, const wchar_t *s2);
Feature Test Macro Requirements for glibc (see feature_test_macros(7)):
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.
The wcscasecmp() function is provided in glibc since version 2.1.
For an explanation of the terms used in this section, see
attributes(7).

POSIX.1-2008. This function is not specified in POSIX.1-2001, and is
not widely available on other systems.
The behavior of wcscasecmp() depends on the LC_CTYPE category of the
current locale.
