wmemcmp(3) Library Functions Manual wmemcmp(3)
NAME
wmemcmp - compare two arrays of wide-characters
LIBRARY
Standard C library (libc, -lc)
SYNOPSIS
#include <wchar.h>
int wmemcmp(const wchar_t s1[.n], const wchar_t s2[.n], size_t n);
DESCRIPTION
The wmemcmp() function is the wide-character equivalent of the mem-
cmp(3) function. It compares the n wide-characters starting at s1 and
the n wide-characters starting at s2.
RETURN VALUE
The wmemcmp() function returns zero if the wide-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 wide-
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
wide-character s1[i] is less than s2[i].
