Constructor & Destructor Documentation

EventObject() [1/2]

rex::kernel::EventObject::EventObject	(	bool	manual_reset_in,
		bool	initial_state )

Parameters

manual_reset_in	True for a notification event, false for a synchronization event.
initial_state	True when the event starts signaled.

EventObject() [2/2]

rex::kernel::EventObject::EventObject ( const X_DISPATCH_HEADER & header )

explicit

Parameters

header

The dispatch header of a title event, whose type and signal state initialize the object.

Member Function Documentation

Pulse()

i32 rex::kernel::EventObject::Pulse

(

)

Signals an event and releases the current waiters.

Returns

The previous state as the kernel reports it, always 1.

Query()

void rex::kernel::EventObject::Query	(	u32 *	out_type,
		u32 *	out_state )

Reads the type and the live state of an event.

Parameters

out_type	Receives 0 for a manual reset event and 1 otherwise, may be null.
out_state	Receives 1 when signaled and 0 otherwise, may be null.

Reset()

i32 rex::kernel::EventObject::Reset ( )

overridevirtual

Returns

The previous state as the kernel reports it, always 1.

Implements rex::kernel::IGuestEvent.

Set()

i32 rex::kernel::EventObject::Set ( )

overridevirtual

Returns

The previous state as the kernel reports it, always 1.

Implements rex::kernel::IGuestEvent.

Member Data Documentation

event

PublishedPtr<rex::platform::Event> rex::kernel::EventObject::event

Host event that carries the signal state and wakes waiters.

manual_reset

std::atomic<bool> rex::kernel::EventObject::manual_reset {false}

True for a notification event, false for a synchronization event that resets on a wait.
