95  * the argument cmd is specified as CL_GET_NETADDRS, and argument arg
96  * is the location of a structure of type cladm_netaddrs_t. The
97  * cladm_num_netaddrs is used as input for the requested number

99  * entries available.

101  * The caller must allocate sufficient memory for the array of
102  * structures of type cladm_netaddr_entry_t and specify the starting
103  * location as cladm_netaddrs_array.  The number of entries included
104  * in the array is determined using cladm with argument fac specified
105  * as CL_CONFIG, argument cmd specified as CL_GET_NUM_NETADDRS, and
106  * argument arg is the location of a structure of type cladm_netaddrs_t.
107  * The determined number of array entries is returned in
108  * cladm_num_netaddrs.

111  * RCM Framework) to Sun Cluster for cluster controlled adapters.
