MPINotify mpiNotifyCreate(MPIEventMask mask,
                           void         *source)

NotifyCreate creates a Notify object that will accept event notifications for the events that are specified in mask. The source argument specifies the initial element in the list of event sources, from which event notification will be accepted. If source is NULL, then event notification will be accepted from all event sources. NotifyCreate is the equivalent of a C++ constructor.
