Variable Documentation

◆ cap_alloc

_Cap_alloc& L4Re::Util::cap_alloc

extern

Capability allocator.

This is the instance of the capability allocator that is used by usual applications.

The capability allocator uses the Counting_cap_alloc, a reference-counting thread-safe capability allocator, that keeps a reference counter for each managed capability selector.
