| Allegro CL version 10.1 Unrevised from 10.0 to 10.1. 10.0 version | ||||||||||
Arguments: &optional no-wait
Reads and processes a single event. This function may be useful to
control the rate of event processing, or in the listen functions of
some types of stream. Returns t if an event was processed, nil if not.
No-wait determines the behavior when there is not currently a pending
event to process. If true, then
process-single-event returns nil immediately;
if nil, it waits until an event arrives.
See event-loop, which provides a loop with calls for processing events and additional functionality for managing threads. In general, you should use event-loop in preference to writing custom loops usign process-single-event.
