process-sleep

Arguments: seconds &optional whostate

process-sleep suspends the current process for at least the number of seconds specified. That number may be any non-negative, non-complex number. While the process sleeps, other processes are allowed to run. The whostate (default "Sleep") is a string which temporarily replaces the process' whostate during the sleep.

When multiprocessing is enabled in the Lisp world (perhaps with a call to start-scheduler), the standard Common Lisp function sleep is changed to be equivalent to process-sleep. Instead of causing the entire Lisp world to suspend execution for the indicated time, only the executing process is suspended. This is usually the desired action.

See multiprocessing.htm for general information on multiprocessing in Allegro CL.
