I don't think dereferecing the pointer is safe.
The arguments to the comparison function are pointers to char* (i.e. char**), so dereferencing them will pass the char* pointers from the char **cfh_list list to strcmp. It's passing pointers to the compared objects to the comparison function as the objects don't necessarily need to be pointers.
