notify_default_wait3()
Predefined function you can register with the Notifier via the
notify_set_wait3_func() call. Causes the required housekeeping to be per-
formed on the process identified by pid when it dies. See the wait(2) man page for
details of the wait and rusage structures.

int *status;
struct rusage *rusage;
notify_dispatch()
Provided to allow programs which are not notification-based to run in an event-driven
environment. Called regularly from within the application’s main loop to allow the
Notifier to go once around its internal loop and dispatch any pending events.
Notify_error
notify_dispatch()
notify_do_dispatch()
Enables implicit dispatching, in which the Notifier dispatches events from within calls
to read(2) or select(2).
Notify_error
notify_do_dispatch()
notify_enable_rpc_svc()
If you use an RPC server that also needs to work with XView, use the XView function
notify_enable_rpc_svc(), and do not call svc_run(). This function takes
an int that tells the notifier whether it should handle RPC requests.
Using this aproach, xv_main_loop() handles incoming RPC requests; dispatching
them just as if svc_run() had been called.
If notify_enable_rpc_svc is enabled, the Notifier checks svc_fdset and
calls svc_getreqset() if a descriptor is readable (a request is coming in). Perfor-
mance is affected by the additional call to svc_getreqset().
void
notify_enable_rpc_svc(bool)
int bool;
