20 !!DESCRIPTION

22
23 The __wcsncmp__ function is the wide-character equivalent
24 of the __strncmp__ function. It compares the
25 wide-character string pointed to by ''s1'' and the
26 wide-character string pointed to by ''s2'', but at most
27 ''n'' wide characters from each string. In each string,
28 the comparison extends only up to the first occurrence of a
29 L'0' character, if any.
30 !!RETURN VALUE
31
32
33 The __wcsncmp__ function returns zero if the
34 wide-character strings at ''s1'' and ''s2'', truncated
35 to at most length ''n'', are equal. It returns an integer
36 greater than zero if at the first differing position
37 ''i'' (''i'' ''n''), the corresponding
38 wide-character ''s1[[i]'' is greater than ''s2[[i]''. It
39 returns an integer less than zero if at the first differing
40 position ''i'' (''i'' ''n''), the
41 corresponding wide-character ''s1[[i]'' is less than
42 ''s2[[i]''.
