from crm/admin/crm_resource.c  (should be mostly self explanatory)

static int
dump_resource_attr(
	const char *rsc, const char *attr, pe_working_set_t *data_set)
{
	node_t *current = NULL;
	resource_t *the_rsc = pe_find_resource(data_set->resources, rsc);
	const char *value = NULL;

	if(the_rsc == NULL) {
		return cib_NOTEXISTS;
	}

	if(g_list_length(the_rsc->running_on) == 1) {
		current = the_rsc->running_on->data;

	} else if(g_list_length(the_rsc->running_on) > 1) {
		fprintf(stderr, "%s is active on more than one node,"
			" returning the default value for %s\n",
			the_rsc->id, crm_str(value));
	}
	
	unpack_instance_attributes(
		the_rsc->xml, attr_set_type, current?current->details->attrs:NULL,
		the_rsc->parameters, NULL, data_set->now);

	if(the_rsc->parameters != NULL) {
		crm_debug("Looking up %s in %s", attr, the_rsc->id);
		value = g_hash_table_lookup(the_rsc->parameters, attr);
	}
	if(value != NULL) {
		fprintf(stdout, "%s\n", value);
		return 0;
	}
	return cib_NOTEXISTS;
}
