struct GNUNET_TESTING_Command GNUNET_TESTING_cmd_barrier_reached	(	const char *	label,
		const char *	barrier_label
	)

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

If this command is synchronous it will block.

Parameters

label	name for command.
barrier_label	The name of the barrier we waited for and which was reached.

Returns

command.
