Instance Method

interrupt

Sends an interrupt signal to the receiver and all of its subtasks.

Declaration

- (void)interrupt;

Discussion

If the task terminates as a result, which is the default behavior, an NSTaskDidTerminateNotification gets sent to the default notification center. This method has no effect if the receiver was already launched and has already finished executing. If the receiver has not been launched yet, this method raises an NSInvalidArgumentException.

It is not always possible to interrupt the receiver because it might be ignoring the interrupt signal. interrupt sends SIGINT.
