NAME

13       wcscmp — compare two wide-character strings
14

SYNOPSIS

16       #include <wchar.h>
17
18       int wcscmp(const wchar_t *ws1, const wchar_t *ws2);
19

DESCRIPTION

21       The functionality described on this reference page is aligned with  the
22       ISO C  standard.  Any  conflict between the requirements described here
23       and the ISO C standard is unintentional. This  volume  of  POSIX.1‐2008
24       defers to the ISO C standard.
25
26       The  wcscmp()  function shall compare the wide-character string pointed
27       to by ws1 to the wide-character string pointed to by ws2.
28
29       The sign of a non-zero return value shall be determined by the sign  of
30       the  difference  between the values of the first pair of wide-character
31       codes that differ in the objects being compared.
32

RETURN VALUE

34       Upon completion, wcscmp() shall return an integer greater  than,  equal
35       to,  or  less than 0, if the wide-character string pointed to by ws1 is
36       greater than, equal to, or less than the wide-character string  pointed
37       to by ws2, respectively.
