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



NAME
       wcsncasecmp - compare two fixed-size wide-character strings, ignoring case

SYNOPSIS
       #define _GNU_SOURCE
       #include <wchar.h>

       int wcsncasecmp(const wchar_t *s1, const wchar_t *s2, size_t n);

DESCRIPTION
       The wcsncasecmp() function is the wide-character equivalent of the strncasecmp(3) function.  It compares the wide-charac-
       ter string pointed to by s1 and the wide-character string pointed to by s2, but at  most  n  wide  characters  from  each
       string, ignoring case differences (towupper(3), towlower(3)).

RETURN VALUE
       The  wcsncasecmp()  function  returns zero if the wide-character strings at s1 and s2, truncated to at most length n, are
       equal except for case distinctions.  It returns a positive integer if truncated s1 is greater than truncated s2, ignoring
       case.  It returns a negative integer if truncated s1 is smaller than truncated 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 wcsncasecmp() depends on the LC_CTYPE category of the current locale.
