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 memcmp(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].
