Abstract
A method and apparatus for processing data when an interrupt is received during processing of a function at a point during the processing at which a portion of the function has been processed then a control parameter is accessed. In response to a control parameter having a value indicting that the function has idempotence, processing of the function is stopped, and information on progress of the function is discarded such that following completion of the interrupt the portion of the function that has already been processed is processed again. In response to the control parameter having a value indicating that the function does not have idempotence, processing of the function is suspended without discarding information on progress of the function that has already been processed such that following completion of the interrupt the processing is resumed from a point that it reached when it was suspended.
