/*
 * \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.
