Synopsis

cc [flags…] -I /usr/cluster/include file
   -L /usr/cluster/lib -l dsdev
#include <rgm/libdsdev.h>

scha_err_t scds_get_rs_hostnames(scds_handle_t handle,
scds_net_resource_list_t **netresource_list);

Description

The scds_get_rs_hostnames() function retrieves a list of hostnames used by the resource. If the resource property Network_resources_used is set, then the hostnames correspond to the network resources listed in Network_resources_used. Otherwise, they correspond to all the network resources in the resource group containing the resource.

This function returns a pointer to the list in netresource_list. It is possible for a resource group to contain no network resources or to contain resources that do not use network resources, so this function can return netresource_list set to NULL.

Free the memory allocated and returned by this function with scds_free_net_list(3HA).

Parameters

The following parameters are supported
