pub struct ThreadedRegistration<H: ThreadedHandler>(_);
Expand description

The registration of a threaded interrupt handler.

Examples

The following is an example of a threaded handler with a ref-counted u32 as data:

use kernel::{
    irq,
    sync::{Ref, RefBorrow},
};

struct Example;

impl irq::ThreadedHandler for Example {
    type Data = Ref<u32>;

    fn handle_threaded_irq(_data: RefBorrow<'_, u32>) -> irq::Return {
        irq::Return::None
    }
}

fn request_irq(irq: u32, data: Ref<u32>) -> Result<irq::ThreadedRegistration<Example>> {
    irq::ThreadedRegistration::try_new(irq, data, irq::flags::SHARED, fmt!("example_{irq}"))
}

Implementations

Registers a new threaded irq handler.

The valid values of flags come from the flags module.
