WCSCASECMP(3)                                       Linux Programmer's Manual                                      WCSCASECMP(3)



NAME
       wcscasecmp - compare two wide-character strings, ignoring case

SYNOPSIS
       #define _GNU_SOURCE
       #include <wchar.h>

       int wcscasecmp(const wchar_t *s1, const wchar_t *s2);

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.

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.
