WMEMCMP(3) Linux Programmer's Manual WMEMCMP(3)

wmemcmp - compare two arrays of wide-characters

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

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.

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].

For an explanation of the terms used in this section, see attributes(7).
