NAME¶

wcscasecmp - 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():

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.

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 during its execution.

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.

SEE ALSO¶
