// Purpose:      Define kernel instrumentation

// Description:  A set of definitions and macros used to implement an

//               instrumentation interface for the kernel.

//               NOTE: Don't use CYG_UNUSED_PARAM (or similar) here to

//               silence warnings about unused variables when using the

//               empty macro definitions. Otherwise this can cause problems

//               with volatile arguments and cause other side-effects.

//               Instead it is up to the caller to ensure that unused

//               arguments don't cause warnings

// Usage:        #include <cyg/kernel/instrmnt.hxx>
