Data Structures
struct	cap_token
	Opaque 64-bit capability token. More...
struct	domain
	The domain struct — the central entity of the DGP kernel. More...
struct	strand
	Strand — the DGP kernel's unit of schedulable execution. More...

Typedefs
using	domain_id
	Opaque domain identifier.

Enumerations
enum class	cap_rights
	Standard access rights usable with any capability type.
enum class	cap_type
	Discriminator for the kind of resource a capability token refers to.
enum class	domain_flags
	Per-domain flags (bitfield).
