class InterruptDispatcher

Defined at line 31 of file ../../zircon/kernel/object/include/object/interrupt_dispatcher.h

Note that unlike most Dispatcher subclasses, this one is further

subclassed, and so cannot be final.

void InitializeWakeEvent ()

Allow subclasses to add/remove the wake event instance from the global diagnostics list at the

appropriate times during initialization and teardown. These methods do not need to be called

unless the subclass needs to be able to wake the system from suspend. See lib/wake-vector.h for

the specific requirements regarding when to initialize and destroy the wake event.

ktl::optional<zx_status_t> BeginWaitForInterrupt (zx_time_t * out_timestamp)

The zx_interrupt_wait operation is broken down into two phases. First, we

BeginWaitForInterrupt, which will handle internal bookkeeping and either return a status code

if the wait operation is finished (success or failure), or it will return nothing if we need to

block and try again later.

Afterwards, if we need to block, we will call DoWaitForInterruptBlock and try again if the

block operation succeeds.
