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*():

      Since glibc 2.10:
          _POSIX_C_SOURCE >= 200809L
      Before glibc 2.10:
          _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.

VERSIONS

The *wcscasecmp*() function is provided in glibc since version 2.1.
