    Those are declarations of pointers to functions.

    /* real function */
    void dumb(int a) { return a; }
    ...

    /* here follows a declaration of func pointer */
    int (*func_ptr)(int);
    int a;

    /* assign it */
    func_ptr=dumb;

    /* use it */
    a=func_ptr(123);

    Any good book about C should cover this. Look for OOP in C also, it's
    frequent use pointers to functions + structs to add classes to C.

    regards,
