Delete a Photon pulse
int PtAppDeletePulse( PtAppContext_t app,
pid_t pulse_pid );
ph
This function deletes the Photon pulse identified by pulse_pid
(and the proxy in QNX 4).
The pulse_pid identifies a pulse created by
PtAppCreatePulse().
The app argument is the address of the application context, a
structure that manages all the data associated with this
application.
This must be specified as NULL,
so that the default context is used.
|
If the
application creates and destroys pulses frequently, the pulse ID
will be reused eventually. At least several hundred pulses can be
safely created and destroyed before that happens. If a pulse ID is
reused but notifications are still generated with the old pulse,
they may or may not be delivered to the new pulse handler. |
