- get the network resources used in a resource group

Synopsis

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

scha_err_t scds_get_rg_hostnames(char *resourcegroup_name,
scds_net_resource_list_t **netresource_list);

scha_err_t  char *resourcegroup_name, scds_net_resource_list_t **netresource_list);

Description

The scds_get_rg_hostnames() function retrieves a list of host names that are used by all the network resources in a resource group. This function returns a pointer to the list in netresource_list. A resource group can contain no network resources or can contain resources that do not use network resources, so these functions can return a netresource_list parameter that is set to NULL.

You can pass the name of any resource group name in the system to scds_get_rg_hostnames(). Use the host names that are returned by scds_get_rg_hostnames() to contact applications that are running in the specified resource group.

Free the memory that is allocated and returned by this function with scds_free_net_list().

Parameters

The following parameters are supported

resourcegroup_name

Name of the resource group for which data is to be retrieved

netresource_list

List of network resources that are used by the resource group
