interrupt handling - fork - exec help!!
I have an interrupt installed in the kernel, generating interrupts nicely and printing kernel messages. But I need a way of handling this at user level, for instance using the fork command so one process is running then whenever the interrupt handler gets an interrupt it acts upon this.
The problem I have is monitoring the handler, and i dont seem to be able to find any examples of this, it is for the parallel port so it is 7.
i have the oreilly book on linux device drivers, but ideally need an example program just to see how it all fits together.
any help or coments would be greatly appreciated!
