Tries to send the file identified by `source` to `destination` as fast as possible. Unless a specific technique is forced it will decide what method to use from the systems capabilities and the filesize. source can be either a port to the inputfile or a filedescriptor of an already opened file. destination can be either a port to the outputfile (socket) or a filedescriptor (socketdesciptor) of an already opened file (socket). When it is a port, any buffered output is flushed via flush-output prior to sending the file. offset If given the procedure seeks to offset bytes and starts to transfer from there on bytes If given it transfers only bytes bytes of data.
