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)):
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
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.

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.
