wmemcmp - compare two arrays of wide-characters
Standard C library (
libc,
-lc)
#include <wchar.h>
int wmemcmp(const wchar_t s1[.n], const wchar_t s2[.n], 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].
