Arm a Photon pulse for delivery
int PtPulseArm( PtAppContext_t app,
pid_t pulse,
struct sigevent *msg );
ph
This function arms a Photon pulse and creates a
“pulse message” to be sent to another process.
The other process can use the pulse message and
MsgDeliverEvent()
to send the pulse.
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.
The pulse argument is a pulse ID returned by
PtAppCreatePulse().
The msg argument points a sigevent that's filled in
by the function.
You'll need to send it to the process that's going to deliver the pulse.
