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
