Function Documentation

pcmk_evaluate_rule()

int pcmk_evaluate_rule	(	xmlNode *	rule,
		const pcmk_rule_input_t *	rule_input,
		crm_time_t *	next_change
	)

Evaluate a single rule, including all its conditions.

Parameters

[in,out]	rule	XML containing a rule definition or its id-ref
[in]	rule_input	Values used to evaluate rule criteria
[out]	next_change	If not NULL, set to when evaluation will change

Returns

Standard Pacemaker return code (pcmk_rc_ok if the rule is satisfied, some other value if it is not)
