Right about oh_evt_queue_push.
See slave, test_agent or ipmidirect plugins source code.
As for resource it is not so simple.
Plugin has no pointer to the domain RPT.
It only has its own RPT that keeps the plugin resources only.
The daemon RPT is managed with events. See openhpid/event.c
For example if you send Hot Swap Event to NOT_PRESENT state, then
the resource RPT entry is removed from the daemom RPT.
