// 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>
//
