> Hello, C99:

So, "char (*libs[n])" would be equivalent to "char *libs[n]", which is an array of n pointers, each pointing to a character ... which is a null-terminated string, I suppose? Like "char **argv" or "char *argv[]" ... but with n

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]))
