wmemcmp - Man Page

compare two arrays of wide-characters

Library

Standard C library (libc, -lc)

Synopsis

#include <wchar.h>

int wmemcmp(const wchar_t *s1, const wchar_t *s2, 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].
