mco_cluster_get_active_nodes

This function returns information about the active nodes in a cluster.

For an overview see page Cluster Applications in C

Prototype

 
    MCO_RET	mco_cluster_get_active_nodes ( /*IN*/ mco_db_h db, 
                          /*OUT*/ mco_cluster_node_info_t* nodes_info ,
                           /*IN/OUT*/ uint2 n_nodes_info )

Arguments

db	Connection to the database.
nodes_info	Array of `mco_cluster_node_info_t` structures which contain information about the active nodes:
n_nodes_info	In input determines the length of the `nodes_info` array (how many elements were allocated), on output contains the number of filled elements

Description

This function returns information about the active nodes in a cluster. (Note: To determine the number of active nodes (and allocate the right size nodes_info array) the application can call mco_cluster_info(db, &cl_info) and use the value of cl_info.n_active_nodes.)

Return Codes

MCO_S_OK	Nodes info returned successfully.
MCO_S_OVERFLOW	If `nodes_info` does not have enough elements for the number of active nodes in the cluster
