Struct ReturnArguments

pub struct ReturnArguments {
    pub upcall_id: UpcallId,
    pub argument0: usize,
    pub argument1: usize,
    pub argument2: usize,
}

This is similar to FunctionCall but for the special case of the Null Upcall for a subscribe.

Because there is no function pointer in a Null Upcall we can only return these values to userspace. This is used to pass around upcall parameters when there is no associated upcall to actually call or userdata.

Fields

upcall_id: UpcallId

Which upcall generates this event.

argument0: usize

The first argument to return.

argument1: usize

The second argument to return.

argument2: usize

The third argument to return.
