Event Interface
The Event library is a utility library provided with Spread, but it is not required that you use it. It is simply provided to avoid everyone having to write their own event handling system.
/* Events priorities */ #define LOW_PRIORITY 0 #define MEDIUM_PRIORITY 1 #define HIGH_PRIORITY 2 /* Event routines */ int E_init(); sp_time E_get_time(); sp_time E_sub_time( sp_time t, sp_time delta_t ); sp_time E_add_time( sp_time t, sp_time delta_t ); int E_compare_time( sp_time t1, sp_time t2 ); int E_queue( void (* func)(), int code, void *data, sp_time delta_time ); int E_dequeue( void (* func)(), int code, void *data ); void E_delay( sp_time t ); int E_attach_fd( int fd, void (* func)(), int code, int priority ); int E_detach_fd( int fd ); void E_set_active_threshold( int priority ); int E_num_active( int priority ); void E_handle_events(); void E_exit_events();
