Name

wmemcmp — compare two arrays of wide-characters

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].
