    void question

    Hey does anybody know if this is possible "void **" Can you actually have a pointer point to a void pointer?

    Can there be a boolen pointer? ex: boolean *test. I have never seen one so i'm not sure.

    thanks...

    Yes, you can have void**. A void-pointer is a generic pointer which you can use to point to variables of different types. In this way you could create a two-dimensional array of chars, ints or whatever.

    If you have type boolean available, then it is possible, depends on your system.

    How does the "void **" work?

    simple.

    a void * will live in some memory location.

    a void * is thus a type

    a "type" * will point to a memory location

    therefore if type = void *
    void ** would point to it.
