process-single-event

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.
