15 The wcsncasecmp() function is the wide-character equivalent of the
16 strncasecmp() function. It compares the wide-character string pointed
17 to by s1 and the wide-character string pointed to by s2, but at most n
18 wide characters from each string, ignoring case differences (towup‐
19 per(), towlower()).
20
22 The wcsncasecmp() function returns zero if the wide-character strings
23 at s1 and s2, truncated to at most length n, are equal except for case
24 distinctions. It returns a positive integer if truncated s1 is greater
25 than truncated s2, ignoring case. It returns a negative integer if
26 truncated s1 is smaller than truncated s2, ignoring case.

29 This function is a GNU extension.

35 The behaviour of wcsncasecmp() depends on the LC_CTYPE category of the
36 current locale.
