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

NAME         top

       wmemcmp - compare two arrays of wide-characters

SYNOPSIS         top

       #include <wchar.h>

       int wmemcmp(const wchar_t *s1, const wchar_t *s2, size_t n);

DESCRIPTION         top

       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         top

       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].
