wmemcmp(3)               Library Functions Manual              wmemcmp(3)

NAME         top

       wmemcmp - compare two arrays of wide-characters

LIBRARY         top

       Standard C library (libc, -lc)

SYNOPSIS         top

       #include <wchar.h>

       int wmemcmp(size_t n;
                   const wchar_t s1[n], const wchar_t s2[n], 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].
