Struct AbsoluteCPtr

pub struct AbsoluteCPtr<C = NoExplicitInvocationContext> { /* private fields */ }

Expand description

A CPtrWithDepth to be resolved in the context of a particular CNode.

AbsoluteCPtr addresses capability slots in a more general way than Cap. It allows one to address any capability slot that is directly addressable from any CNode that is directly addressible in the current thread’s CSpace. Furthermore, it allows one to address capability slots that contain CNodes by limiting the lookup depth to prevent the kernel’s lookup procedure from descending into the CNode contained in that slot.

seL4_CNode_* capability invocations are methods of AbsoluteCPtr rather than Cap.

In addition to AbsoluteCPtr::new, the following methods can be used to construct an AbsoluteCPtr:
