(main-loop-step [poll? any/c]) -> (or/c boolean? symbol? integer?)procedure

Runs a step of the IUP main loop and returns the status code from the processing. If poll? is true, the call returns immediately with a false result in case there are no events to process. If poll? is false, the call does not return until at least one event has been processed.
