The function
wait-processing-events
does not return until one of two conditions is met:
nil
.
t
.wait-reason provides the value returned by process-whostate when called on the current process.
wait-function is called periodically with arguments wait-args . wait-function may be called many times and in several places. Therefore wait-function should be fast and make no assumptions about its dynamic context.
wait-processing-events
processes all events sent to the current process, including system events such as window messages on MS Windows, and objects sent by other processes via process-send. In the latter case, the objects must be lists of the form
(
function
.
arguments
)
, which cause
function
to be applied to
arguments
(the values are discarded).
wait-processing-events
is a useful alternative to
sleep
in a situation where you want to process events to see window updates and so on.
