◆ pcmk_ticket_remove_attr()

int pcmk_ticket_remove_attr	(	xmlNodePtr *	xml,
		const char *	ticket_id,
		GList *	attr_delete,
		bool	force
	)

Remove the given attribute(s) from a ticket.

Parameters

[in,out]	xml	The destination for the result, as an XML tree
[in]	ticket_id	Ticket to remove attributes from
[in]	attr_delete	A list of attribute names
[in]	force	Attempting to remove the granted attribute of `ticket_id` will cause this function to return `EACCES` unless `force` is set to `true`

Returns: Standard Pacemaker return code

Definition at line 422 of file pcmk_ticket.c.

◆ pcmk_ticket_set_attr()

int pcmk_ticket_set_attr	(	xmlNodePtr *	xml,
		const char *	ticket_id,
		GHashTable *	attr_set,
		bool	force
	)

Set the given attribute(s) on a ticket.

Parameters

[in,out]	xml	The destination for the result, as an XML tree
[in]	ticket_id	Ticket to set attributes on
[in]	attr_set	A hash table of attributes, where keys are the attribute names and the values are the attribute values
[in]	force	Attempting to change the granted status of `ticket_id` will cause this function to return `EACCES` unless `force` is set to `true`

Returns: Standard Pacemaker return code

Note: If no ticket_id attribute exists but attr_set is non-NULL, the ticket will be created with the given attributes.

Definition at line 490 of file pcmk_ticket.c.

◆ pcmk_ticket_state()

int pcmk_ticket_state	(	xmlNodePtr *	xml,
		const char *	ticket_id
	)

Return a ticket's state XML.

Parameters

[in,out]	xml	The destination for the result, as an XML tree
[in]	ticket_id	Ticket to find state for, or `NULL` for all tickets

Returns: Standard Pacemaker return code

Note: If ticket_id is not NULL and more than one ticket exists with that ID, this function returns pcmk_rc_duplicate_id.

Definition at line 539 of file pcmk_ticket.c.

◆ pcmk_verify()

int pcmk_verify	(	xmlNodePtr *	xml,
		const char *	cib_source
	)

Verify that a CIB is error-free or output errors and warnings.

This high-level function essentially implements crm_verify(8). It operates on an input CIB file, which can be inputted through one of several ways. It writes out XML-formatted output.

Parameters

[in,out]	xml	The destination for the result, as an XML tree
[in]	cib_source	Source of the CIB: NULL -> use live cib, "-" -> stdin "<..." -> xml str, otherwise -> xml file name

Returns: Standard Pacemaker return code
