		char *	ipc_name,
		unsigned int	message_timeout_ms
	)

Get pacemakerd status.

		pe_node_t *	node,
		GHashTable *	overrides,
		pe_working_set_t *	data_set

pcmk_simulate()

int pcmk_simulate	(	xmlNodePtr *	xml,
		pe_working_set_t *	data_set,
		pcmk_injections_t *	injections,
		unsigned int	flags,
		unsigned int	section_opts,
		char *	use_date,
		char *	input_file,
		char *	graph_file,
		char *	dot_file
	)

Simulate a cluster's response to events.

This high-level function essentially implements crm_simulate(8). It operates on an input CIB file and various lists of events that can be simulated. It optionally writes out a variety of artifacts to show the results of the simulation. Output can be modified with various flags.

Parameters

[in,out]	xml	The destination for the result, as an XML tree.
[in,out]	data_set	Working set for the cluster.
[in]	events	A structure containing cluster events (node up/down, tickets, injected operations)
[in]	flags	A bitfield of :pcmk_sim_flags to modify operation of the simulation.
[in]	section_opts	Which portions of the cluster status output should be displayed?
[in]	use_date	The date to set the cluster's time to (may be NULL).
[in]	input_file	The source CIB file, which may be overwritten by this function (may be NULL).
[in]	graph_file	Where to write the XML-formatted transition graph (may be NULL, in which case no file will be written).
[in]	dot_file	Where to write the dot(1) formatted transition graph (may be NULL, in which case no file will be written). See pcmk__write_sim_dotfile().

Returns

Standard Pacemaker return code
