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.
