Inter Process Communication

Warning

Experimental features:

• May be replaced, updated, or removed at any time.

• Do not require maintaining API/ABI stability of their own additions over time.

• Do not require conformance testing of their own additions.

Motivation

This extension introduces functionality for allowing processes to share common objects, such as device USM memory allocations. Doing so lets processes actively communicate with each other through the devices, by explicitly managing handles that represent shareable objects for inter-process communication.
