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.

NAME

       setsourcefilter() - set IP multicast source filter state

SYNOPSIS

DESCRIPTION

       This  function  sets the multicast source filter state for an IPv4 or IPv6 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 pro-
       vided.  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 or and the socket type must be

       interface Holds the interface index of a local interface, or zero.  If set to zero, 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	 Points to either a sockaddr_in structure (for IPv4) or a sockaddr_in6 structure (for IPv6) that holds the IP multicast address of
		 the group.

       grouplen  Holds the size of the structure pointed to by the group argument.

       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 sockaddr_storage structures containing the IP addresses to include or exclude depending on the filter mode.
		 The sockaddr_storage structures will contain either a sockaddr_in structure (for IPv4 addresses) or a sockaddr_in6 structure (for
		 IPv6 addresses, including IPv4-mapped IPv6 addresses); the address family must match that of the group argument.

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 (for IPv4), or
				    and (for IPv6).

	      The address family of the
				    group argument is not supported.

	      Trying to leave an unjoined group.

	      group		    does not hold an IP multicast address; or slist contains an invalid source address; or  the  specified  filter
				    mode  is not valid; or interface contains an invalid interface index; or grouplen is not valid; or the address
				    family of a source address in the slist argument does not match the address family of the group argument.
