Chapter 7: User-Level Interrupts
The user-level interrupt (ULI) facility complements the ability to perform programmed I/O (PIO) from user space. You can use PIO to initiate a device action that leads to a device interrupt, and you can intercept and handle the interrupt in your program. For function prototypes and other details, see the uli(3) reference page.
