LAN_GET_MULTI(9r)
NAME
  LAN_GET_MULTI - Network: Returns a pointer to the next enabled multicast
  address

SYNOPSIS
  #include <io/dec/netif/lan_common.h>


  int LAN_GET_MULTI(
	  struct lan_multi *lmt,
	  unsigned char *maddr,
	  int index_v );

ARGUMENTS
  lmt Specifies a pointer to the multicast table.

  maddr
      Specifies a pointer to hold the multicast address returned by the
      interface.

  index_v
      Specifies an index value for the multicast table.

DESCRIPTION
  The LAN_GET_MULTI() routine returns a pointer to the next enabled multicast
  address. The search begins at the index specified by the index_v argument.
  When this routine completes, the index_v argument will contain the index of
  the location one past where the returned multicast address was found. You
  can use this interface to return all addresses in a multicast table. For
  example:

       int i, j;
       unsigned char *maddr;

       j = o;
       for (i = 0; i < lmt->lan_nmulti; i++)
	   LAN_GET_MULTI(lmt, maddr, j);
	   if (maddr != NULL)
	       printf("Multicast %s enabled\n", ether_sprintf(maddr));

       {









RETURN VALUES
  On successful completion, the LAN_GET_MULTI() routine returns a pointer to
  the next enabled multicast address.
