NAME

       setipv4sourcefilter() - set IPv4 multicast source filter state

SYNOPSIS

DESCRIPTION

       This  function  sets  the multicast source filter state for an IPv4 multicast group on a given socket.  This function can be used to join a
       multicast group by specifying a filter mode of (with or without a source list), or by specifying a filter mode of with a  non-empty  source
       list.   If  the	multicast group is already joined, this function replaces the existing filter mode and source list with the ones provided.
       This function can be used to leave a multicast group by specifying a filter mode of and an empty source list.

   Parameters
       s	 Specifies the descriptor identifying the socket.  The socket address family must be and the socket type must be

       interface Holds the IPv4 address of a local interface, or If set to the system chooses a multicast group by matching the multicast  address
		 only;	or  when  joining  a group, the system chooses the interface that datagrams for the group would be sent from, based on the
		 routing configuration.

       group	 Holds the IPv4 multicast address of the group.

       fmode	 Identifies the filter mode.  The value of this field must be either or which are defined in

       numsrc	 Holds the number of source addresses in the slist array.

       slist	 Points to an array of IPv4 addresses of sources to include or exclude depending on the filter mode.

RETURN VALUES

       returns the following values:

	      Successful completion.

	      Failure.
		   is set to indicate the error.

ERRORS

       If fails, is set to one of the following values:

	      The argument	    s is not a valid descriptor.

	      This function is not supported by the socket type.

	      Insufficient memory is available for internal
				    system data structures.

	      numsrc		    exceeds the maximum number of sources allowed, as determined by the ndd tunable parameters and

	      The specified IP address is not a local interface address; or
				    trying to leave an unjoined group.

	      group		    is not an IPv4 multicast address; or slist contains an invalid source address; or the specified filter mode is
				    not valid.
