I would be very surprised if UNIX system allowed a user process to access
ports directly. If you are writing a driver or kernal routine in C,
procedures like the ones in your example could be used. Turbo C,
for example, will generate in-line code for inport() and outport()
calls. However, there is no standard here. You may write your own
in assembler or see if your C library already has them.
