Number of the PXROS-HR ticks after which the job is executed.


















handler




Pointer to the handler function to be executed.

DESCRIPTION










PxDelayResched_Pxhnd cancels a potential delay job associated with delay. If ticks is not zero, PXROS schedules activation of the handler call handler(arg) after ticks PXROS ticks and associates this delay job with delay object. The PxDelayResched_Pxhnd can only be called from handler level, otherwise PXERR_PXHND_ILLCALL error is returned.
