Typedef Documentation

typedef struct _R_EventLoop R_EventLoop

A synonym for the main event loop structure

typedef int(* R_IdleFunc)(void *)

A type definition for idle/background action routines. They take a single argument which is an arbitrary C value which it is expected to understand. This is specified when the action is registered with the event handler. The routine is expected to return an integer which if non-zero indicates that it should be re-registered so that it can be called again.

typedef R_IdleFunc R_TimerFunc

A definition for the timer action routines. This is the same as R_IdleFunc.
