/*

|
* \brief IRQ session interface
|
|
* \author Christian Helmuth

* \date 2007-09-13
|
|
*
|
|
* An open IRQ session represents a valid IRQ attachment/association.
|
|
* Initially, the interrupt is masked and will only occur if enabled. This is
|
|
* done by calling wait_for_irq(). When the interrupt is delivered to the
|
|
* client, it was acknowledged and masked at the interrupt controller before.
|
|
*
|
|
* Disassociation from an IRQ is done by closing the session.
