NAME

wmemcmp - compare two arrays of wid-characters

LIBRARY

Standard C library (libc,~-lc)

SYNOPSIS

#include <wchar.h>
int wmemcmp(size_t n;
            const wchar_t s1[n], const wchar_t s2[n], size_t n);

DESCRIPTION

The wmemcmp() function is the wid-character equivalent of the memcmp(3) function. It compares the n wid-characters starting at s1 and the n wid-characters starting at s2.

RETURN VALUE

The wmemcmp() function returns zero if the wid-character arrays of size n at s1 and s2 are equal. It returns an integer greater than zero if at the first differing position i (i < n), the corresponding wid-character s1[i] is greater than s2[i]. It returns an integer less than zero if at the first differing position i (i < n), the corresponding wid-character s1[i] is less than s2[i].
