Function Documentation

pcmk_cluster_connect()

int pcmk_cluster_connect

(

pcmk_cluster_t *

cluster

)

Definition at line 81 of file cluster.c.

pcmk_cluster_disconnect()

int pcmk_cluster_disconnect

(

pcmk_cluster_t *

cluster

)

Disconnect from the cluster layer.

Parameters

[in,out]

cluster

Cluster object to disconnect

Returns

Standard Pacemaker return code

Definition at line 116 of file cluster.c.

pcmk_cluster_free()

void pcmk_cluster_free

(

pcmk_cluster_t *

cluster

)

Free a pcmk_cluster_t object and its dynamically allocated members.

Parameters

[in,out]

cluster

Cluster object to free

Definition at line 163 of file cluster.c.

pcmk_cluster_layer_text()

const char * pcmk_cluster_layer_text

(

enum pcmk_cluster_layer

layer

)

Get a log-friendly string equivalent of a cluster layer.

Parameters

[in]

layer

Cluster layer

Returns

Log-friendly string corresponding to layer

Definition at line 357 of file cluster.c.

pcmk_cluster_new()

pcmk_cluster_t * pcmk_cluster_new

(

void

)

Allocate a new pcmk_cluster_t object.

Returns

A newly allocated pcmk_cluster_t object (guaranteed not NULL)

Note

The caller is responsible for freeing the return value using pcmk_cluster_free().

Definition at line 148 of file cluster.c.

pcmk_cluster_set_destroy_fn()

int pcmk_cluster_set_destroy_fn	(	pcmk_cluster_t *	cluster,
		void(*	fn )(gpointer) )

Set the destroy function for a cluster object.

Parameters

[in,out]	cluster	Cluster object
[in]	fn	Destroy function to set

Returns

Standard Pacemaker return code

Definition at line 184 of file cluster.c.

pcmk_get_cluster_layer()

enum pcmk_cluster_layer pcmk_get_cluster_layer

(

void

)

Get and validate the local cluster layer.

If a cluster layer is not configured via the PCMK__ENV_CLUSTER_TYPE local option, this will try to detect an active cluster from among the supported cluster layers.

Returns

Local cluster layer

Note

This will fatally exit if the configured cluster layer is invalid.
