Function

RBsignal_accumulator_value_handled

Declaration [src] 

gboolean
rb_signal_accumulator_value_handled (
  GSignalInvocationHint* hint,
  GValue* return_accu,
  const GValue* handler_return,
  gpointer dummy
)

Description [src]

A GSignalAccumulator that aborts the signal emission after the first handler to return a value, and returns the value returned by that handler. This is the opposite behaviour from what you get when no accumulator is specified, where the last signal handler wins.

This function is not directly available to language bindings.
