Q: What does
typedef int (*funcptr)();mean?
A: It defines a typedef, funcptr, for a pointer to a function (taking unspecified arguments) returning an int. It can be used to declare one or more pointers to functions:
funcptr pf1, pf2;which is equivalent to the more verbose, and perhaps harder to understand
int (*pf1)(), (*pf2)();See also questions 1.21, 4.12, and 15.11.
