NAME

6       wcsncmp - compare part of two wide-character strings
7

SYNOPSIS

9       #include <wchar.h>
10
11       int wcsncmp(const wchar_t *ws1, const wchar_t *ws2, size_t n);

DESCRIPTION

15       The  wcsncmp()  function  shall  compare not more than n wide-character
16       codes (wide-character codes that follow a null wide-character code  are
17       not  compared) from the array pointed to by ws1 to the array pointed to
18       by ws2.
19
20       The sign of a non-zero return value shall be determined by the sign  of
21       the  difference  between the values of the first pair of wide-character
22       codes that differ in the objects being compared.
23

RETURN VALUE

25       Upon successful completion, wcsncmp() shall return an  integer  greater
26       than,  equal  to, or less than 0, if the possibly null-terminated array
27       pointed to by ws1 is greater than, equal to, or less than the  possibly
28       null-terminated array pointed to by ws2, respectively.
