Description copied from interface: Socket

get a socket option

Specified by:

getsockopt in interface Socket

Parameters:

arg0 - socket descriptor

arg4 - On return, the by-reference int will contain the size of the option_value data

Returns:

A -1 is returned if an error occurs, otherwise the return value is a descriptor referencing the socket.

bind

public int bind(int arg0,
                Socket.sockaddr_in arg1,
                int arg2)

Description copied from interface: Socket

bind a socket to a port

Specified by:

bind in interface Socket

Parameters:

arg0 - socket descriptor

arg1 - ptr to a sockaddr_in buffer

arg2 - size of sockaddr_in

Returns:

A -1 is returned if an error occurs, otherwise the return value is a descriptor referencing the socket.

listen

public int listen(int arg0,
                  int arg1)

Description copied from interface: Socket

listen for connections on socket

Specified by:

listen in interface Socket

Parameters:

arg0 - socket descriptor

Returns:

A -1 is returned if an error occurs, otherwise the return value is a descriptor referencing the socket.

shutdown

public int shutdown(int arg0,
                    int arg1)

Description copied from interface: Socket

initiate a connection on a socket.

Specified by:

shutdown in interface Socket

Parameters:

arg0 - socket descriptor

arg1 - If how is SHUT_RD, further receives will be disallowed. If how is SHUT_WR, further sends will be disallowed. If how is SHUT_RDWR, further sends and receives will be disallowed.

Returns:

A -1 is returned if an error occurs, otherwise zero is returned

inet_ntop

public String inet_ntop(int arg0,
                        IntByReference arg1,
                        Pointer arg2,
                        int arg3)

Description copied from interface: Socket

Takes an IPv4 Internet address and returns string representing the address in `.' notation

Specified by:

inet_ntop in interface Socket

Parameters:

arg0 - family (should be AF_INET)

arg1 - a pointer to the src internet address

arg2 - a pointer to tmp buffer used to store characters for the result.

arg3 - the size of the tmp dst buffer

Returns:

String (created from the characters in the dst buffer)

socket

public int socket(int arg0,
                  int arg1,
                  int arg2)

Description copied from interface: Socket

socket() creates an endpoint for communication and returns a descriptor.

Specified by:

socket in interface Socket

Parameters:

arg0 - specifies a communications domain within which communication will take place; this selects the protocol family which should be used. The currently understood formats are: AF_UNIX, AF_INET, AF_ISO, AF_NS, AF_IMPLINK

arg1 - specifies the semantics of communication. Currently defined types are: SOCK_STREAM, SOCK_DGRAM, SOCK_RAW, SOCK_SEQPACKET, SOCK_RDM

arg2 - The protocol number to use is particular to the communication domain in which communication is to take place; see protocols(5).

Returns:

A -1 is returned if an error occurs, otherwise the return value is a descriptor referencing the socket.

accept

public int accept(int arg0,
                  Socket.sockaddr_in arg1,
                  IntByReference arg2)

Description copied from interface: Socket

accept a connection from a client

Specified by:

accept in interface Socket

Parameters:

arg0 - socket descriptor

arg1 - ptr to a SockAddr_In buffer that will contain the address of the remote client

arg2 - pointer to int containing the size of an IP address

Returns:

A -1 is returned if an error occurs, otherwise the return value is a descriptor referencing the socket.

connect
