		unsigned int	asynchronous_finish,
		unsigned int	node_number,
		unsigned int	running_on_master,
		GNUNET_TESTING_cmd_helper_write_cb	write_message
	)

Create command.

If this command is executed the the process is signaling the master process that it reached a barrier.

Parameters

label	name for command.
barrier_label	The name of the barrier we wait for (if finishing asynchronous) and which will be reached.
asynchronous_finish	If GNUNET_YES this command will not block.
node_number	The global numer of the node the cmd runs on.
running_on_master	Is this cmd running on the master loop.
write_message	Callback to write messages to the master loop.

Returns

command.
