Instance Method Details

- (Object) break_loop

Abort the active event_base loop immediately.

It will abort the loop after the next event is completed; event_base_loopbreak() is typically invoked from this event's callback. This behavior is analogous to the "break;" statement. Subsequent invocations of event_loop() will proceed normally.




# File 'ext/libevent_ext/base.c'

static VALUE t_break_loop(VALUE self) {
  Libevent_Base *base;
  int status;

  Data_Get_Struct(self, Libevent_Base, base);
  status = event_base_loopbreak(base->ev_base);

  return (status == -1 ? Qfalse : Qtrue);
}

- (Object) dispatch

Event dispatching loop.

This loop will run the event base until either there are no more added events, or until something calls Libevent::Base#break_loop or Base#exit_loop.

See Also:




# File 'ext/libevent_ext/base.c'

static VALUE t_dispatch(VALUE self) {
  Libevent_Base *base;
  int status;

  Data_Get_Struct(self, Libevent_Base, base);
  status = event_base_dispatch(base->ev_base);

  return INT2FIX(status);
}

- (Object) exit_loop

TODO:

specified time is not implemented

Exit the event loop after the specified time




# File 'ext/libevent_ext/base.c'

static VALUE t_exit_loop(VALUE self) {
  Libevent_Base *base;
  int status;

  Data_Get_Struct(self, Libevent_Base, base);
  status = event_base_loopexit(base->ev_base, NULL);

  return (status == -1 ? Qfalse : Qtrue);
}

- (Object) trap_signal(name, &block)

Create new signal with handler as block and add signal to event base

Parameters:

  • name (String) —

    of signal
