Input and output is dependent on hardware. The time units are machine cycles, which depends both on the oscillator frequency and the oscillator periods to machine cycle conversion factor. This code puts the processor into 'idle' mode, where code execution is stopped and resumed via an interrupt.

A similar trick can be used to wait a certain number of milliseconds. The <code>ping</code> utility includes a <code>/w</code> option which specifies the timeout to wait for a reply. This coupled with an unreachable address (where the full timeout will be needed) leads to the following:

While this function does tie up execution (but not with a busy wait), the Mathematica front end remains fully functional and can be used to stop the sleeping with Evaluation -> Abort Evaluation.

Note that sleep() is entirely inappropriate for GUI applications, which should instead set a routine to resume processing
(that would be timer_cb below), activate a timer (set RUN to true), and relinquish control to the event loop. Another
excellent way to perform extended processing without making an application unresponsive is via an IDLE_ACTION, provided
that also regularly relinquishes control to the event loop, and can pick up where it left off when next invoked.

This sleep subroutine takes the number of seconds to sleep as a parameter.
The actual linux syscall that I use to implement this takes a time struct (seconds at the first qword and nanoseconds at the second) as the first argument. Optionally you can pass another time stuct as a second argument. In the event that the sleep is interrupted by a system event, linux will fill this second struct with the remaining time so the syscall can be called again with the remaining sleep time.
