Struct FunctionCall

Source
pub struct FunctionCall {
    pub source: FunctionCallSource,

    pub argument2: usize,
    pub argument3: CapabilityPtr,
    pub pc: CapabilityPtr,
}
Expand description

Struct that defines a upcall that can be passed to a process. The upcall takes four arguments that are Driver and upcall specific, so they are represented generically here.

Likely these four arguments will get passed as the first four register values, but this is architecture-dependent.

A FunctionCall also identifies the upcall that scheduled it, if any, so that it can be unscheduled when the process unsubscribes from this upcall.

Fields§

§source: FunctionCallSource

Whether the kernel called this directly or this is an upcall.

§argument0: usize

The first argument to the function.

§argument1: usize

The second argument to the function.

§argument2: usize

The third argument to the function.

§argument3: CapabilityPtr

The userdata provided by the process via subscribe

§pc: CapabilityPtr

The PC of the function to execute.
