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).
