WCSCASECMP(3) Linux Programmer's Manual WCSCASECMP(3)NAMEwcscasecmp - compare two wide-character strings, ignoring case
SYNOPSIS
#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:
_XOPEN_SOURCE >= 700 || _POSIX_C_SOURCE >= 200809L
Before glibc 2.10:
_GNU_SOURCE
DESCRIPTION
The wcscasecmp() function is the wide-character equivalent of the str‐
casecmp(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 posi‐
tive integer if s1 is greater than s2, ignoring case. It returns a
negative integer if s1 is smaller than s2, ignoring case.
VERSIONS
The wcscasecmp() function is provided in glibc since version 2.1.
ATTRIBUTES
Multithreading (see pthreads(7))
The wcscasecmp() function is thread-safe with exceptions. It can be
safely used in multithreaded applications, as long as setlocale(3) is
not called to change the locale.
CONFORMING TO
POSIX.1-2008. This function is not specified in POSIX.1-2001, and is
not widely available on other systems.
NOTES
The behavior of wcscasecmp() depends on the LC_CTYPE category of the
current locale.
