PtrArray.findWithEqualFunc

Checks whether needle exists in haystack, using the given equal_func. If the element is found, TRUE is returned and the element’s index is returned in index_ (if non-NULL). Otherwise, FALSE is returned and index_ is undefined. If needle exists multiple times in haystack, the index of the first instance is returned.

equal_func is called with the element from the array as its first parameter, and needle as its second parameter. If equal_func is NULL, pointer equality is used.
