+These functions perform case-insensitive comparison of wide-character
+strings
+.Fa ws1
+and
+.Fa ws2 .
+Pairs of wide-characters from each of
+.Fa ws1
+and
+.Fa ws2
+are compared consecutively, ignoring differences in case (if the
+.\"POSIX\." locale upper case characters are treated as lower case).  If
+the two values are different, the comparision stops and either
+a negative value is returned if the character from
+.Fa ws1
+is less than that from
+.Fa ws2 ,
+or a positive is returned if the character from
+.Fa ws1
+is greater than that from
+.Fa ws2 .
+The comparison also stops if both characters are null wide-characters,
+or, in the case of
+.Fn wcsncasecmp
+and
+.Fn wcsncasecmp_l ,
+after
+.Fa n
+comparisons have been made without finding a difference.  In either of
+these two cases, 0 is returned.

+The
