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



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

SYNOPSIS
       #define _GNU_SOURCE
       #include <&lt;wchar.h>&gt;

       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-character 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 (towup-
       per(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
       This function is a GNU extension.

NOTES
       The behavior of wcsncasecmp() depends on the LC_CTYPE category  of  the
       current locale.
