C++ Irq interface.
The Irq class provides access to abstract interrupts provided by the microkernel. Interrupts may be
Irq objects can be created using a factory, see the L4::Factory API (L4::Factory::create()).
For the C interface refer to the IRQs API for an overview.

Irq::wait() and Irq::receive() operations already include an unmask(), do not use an extra unmask() in these cases.
