Class protocol:

 initialize

initialize for the OS we are running on

 initializeConcreteClass

initialize for the OS we are running on

 reinitialize

initialize for the OS we are running on

Instance protocol:

 finalize

a filedescriptor was garbage collected - close the underlying file

 readBytes: count into: aByteBuffer startingAt: startAddress

read count bytes into a byte-buffer;
Return the number of bytes read (negative on error)

** This method raises an error - it must be redefined in concrete classes **

 writeBytes: count from: aByteBuffer startingAt: startAddress

write count bytes from a byte-buffer;
Return the number of bytes written (negative on error)

** This method raises an error - it must be redefined in concrete classes **

 close

close the file

 closeFile

close the underlying file

** This method raises an error - it must be redefined in concrete classes **
