Detailed Description

Interrupt Handler Support.

This include file describe the data structure and the functions implemented by rtems to write interrupt handlers.

This code is heavily inspired by the public specification of STREAM V2 that can be found at:

• http://www.chorus.com/Documentation/index.html by following the STREAM API Specification Document link.
