atalk_ct_memcmp()

int atalk_ct_memcmp ( const void * a, const void * b, size_t n )

extern

Constant-time memory equality check.

Compares exactly n bytes and returns 0 if the buffers are equal, non-zero if they differ.

Note

Unlike memcmp(), this function does not provide lexicographic ordering and must not be used for sorting.

Returns

0 if the buffers are equal, non-zero if they differ.
