Function Documentation

int ix_connect_remote	(	int	socket,
		struct in_addr *	addr,
		unsigned short	port
	)

connect to remote addr and port in host order via socket (which is usually made with ix_make_..._socket with no special port given)

Parameters:

	socket	local socket to connect
	addr	remote address you want to connect to socket (in case of udp socket this may be the default address to send datagramms)
	port	remote port (net-order) you want to connect to socket (in case of udp socket this may be the default port to send datagramms)

Returns:

• 0: OK
• <0: error

int ix_make_tcp_dyn_socket

(

int *

port

)

returns tcp socket bind to a dynamic port

Parameters:

port

pointer where to store port in hostorder

Returns:

• socketfd
• <0: error

int ix_make_tcp_socket

(

int

port

)

returns tcp socket bind to port

Parameters:

port

port in hostorder. If value is 0 some arbitrary port is used (this is usually used for outgoing connections).

Returns:

• socketfd
• <0: error

int ix_make_udp_socket

(

int

port

)

returns udp socket bind to port

Parameters:

port

port in hostorder. If value is 0 some arbitrary port is used (this is usually used for outgoing connections).

Returns:

• socketfd
• <0: error

int ix_socket_join_multicast	(	int	socket,
		struct in_addr	addr
	)

join a udp/ip socket to a multicast group

Parameters:

	socket	to join
	multicast_addr	multicast group

Returns:

• 0: OK
• <0: error
