Struct IRQGate

pub struct IRQGate {
    prologue: unsafe fn(),
    epilogue_entrant: Option<EpilogueEntrant>,
}

describes a device interrupt handler routine. This is used to register a device driver to an interrupt line (see plugbox). Device drivers code should implement the IRQHandler or IRQHandlerEpilogue trait.

Fields

prologue: unsafe fn()

epilogue_entrant: Option<EpilogueEntrant>

Implementations

impl IRQGate

pub unsafe fn call_prologue(&self)

pub fn get_epilogue(&self) -> Option<EpilogueEntrant>

the epilogue function should never be directly called from the IRQGate. Instead you need to get an epilogue entrant, and insert it into the epilogue queue, so that the execution of epilogues are synchronized.

Trait Implementations

impl Clone for IRQGate

fn clone(&self) -> IRQGate

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
