Valid parameter type examples: int a[][3], int b[][2][3]. These are like int(*a)[3] and int(*b)[2][3] if I am not mistaken.

Hello, C99:

/*      Find all paths that may contain dynamic libraries.
 *      Returns their count. libs may be NULL to get allocation size
static size_t _sqo_lib_paths(size_t const n, char (*libs[n]))
