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


SYNOPSIS

       #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 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, towlower).


RETURN VALUE

       The wcsncasecmp function returns zero if the  wide-charac­
       ter  strings  at s1 and s2, truncated to at most length n,
       are equal except for case distinctions. It returns a posi­
       tive 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 behaviour of wcsncasecmp depends on the LC_CTYPE cate­
       gory of the current locale.
