libraw1394 handle
port
port to connect to (corresponds to index of struct raw1394_portinfo)
This function connects the handle to the port given (as queried with
raw1394_get_port_info
). If successful, raw1394_get_port_info
and
raw1394_set_port
are not allowed to be called afterwards on this handle.
To make up for this, all the other functions (those handling asynchronous and
isochronous transmissions) can now be called.
