wcscasecmp(3) Linux Man Page

Name

wcscasecmp - compare two wide-character strings, ignoring case

Library

Standard C library ( libc ", " -lc )

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.
