fcreate

public void fcreate(boolean stream)
             throws IOException

Parameters:

stream - if true, create a stream socket; otherwise, create a datagram socket.

Throws:

IOException - if an I/O error occurs while creating the socket.

See Also:

SocketImpl.create(boolean)

fgetInputStream

public InputStream fgetInputStream()
                            throws IOException
