// Purpose:
// This file contains default no-op definitions for the sampling
// start/stop functions so that an application can link with
// -lhpctoolkit without having to #ifdef all of the calls.
//
// The static case must use weak symbols, but the dynamic case can use
// strong or weak (LD_PRELOAD supersedes strong/weak).
