Get the file PCTIME13.ZIP from SimTel mirrors, directory SimTel/msdos/c.
It includes an example of timer programming with DJGPP.
It might also help if you tell how many interrupts per second would you
need to process in your project. The specific technique best suited to
your problem might depend on that.
