Member Function Documentation

◆ cloneForDelivery()

Event * LinuxAmd64Signal::AsyncEvent::cloneForDelivery ( )

overridevirtual

Returns the instance to enqueue for one delivery. Most events enqueue themselves; signal dispositions return an independently owned snapshot.

Reimplemented from SignalEvent.

Definition at line 418 of file linux-amd64-signal.cc.

References Event::isDeletable().

◆ cloneForDisposition()

SignalEvent * LinuxAmd64Signal::AsyncEvent::cloneForDisposition ( )

overridevirtual

Copies a stable signal-disposition event without slicing subclasses.

Reimplemented from SignalEvent.

Definition at line 425 of file linux-amd64-signal.cc.

◆ deliverAtUserReturn() [1/2]

Event::UserReturnDelivery LinuxAmd64Signal::AsyncEvent::deliverAtUserReturn ( InterruptState & )

overridevirtual

Delivers this event by editing an interrupt return frame in place.

Reimplemented from Event.

Definition at line 429 of file linux-amd64-signal.cc.

References ProcessorBase::information().

◆ deliverAtUserReturn() [2/2]

Event::UserReturnDelivery LinuxAmd64Signal::AsyncEvent::deliverAtUserReturn ( SyscallState & )

overridevirtual

Delivers this event by editing a syscall return frame in place.

Reimplemented from Event.

Definition at line 454 of file linux-amd64-signal.cc.

References ProcessorBase::information().

◆ getFlags()

uint32_t LinuxAmd64Signal::AsyncEvent::getFlags ( ) const

◆ getRestorer()

uintptr_t LinuxAmd64Signal::AsyncEvent::getRestorer ( ) const

inline

Definition at line 51 of file linux-amd64-signal.h.

◆ requiresExactUserReturnState()

bool LinuxAmd64Signal::AsyncEvent::requiresExactUserReturnState ( ) const

inlineoverridevirtual

Returns true when this event cannot run without the raw user context.

Reimplemented from Event.

Definition at line 38 of file linux-amd64-signal.h.
