◆ GNUNET_TESTING_cmd_rewind_ip()

struct GNUNET_TESTING_Command GNUNET_TESTING_cmd_rewind_ip	(	const char *	label,
		const char *	target_label,
		unsigned int	counter
	)

Make the instruction pointer point to target_label only if counter is greater than zero.

Note that the command that will be executed next in this case is the one AFTER target_label, as the command we jump to is skipped by the advancing IP after the rewind.

Parameters

label	command label
target_label	label of the new instruction pointer's destination after the jump; must be before the current instruction (and the command at the target_label itself will not be run, but the one afterwards)
counter	counts how many times the rewinding is to happen.
