// The number of times to loop thru the tests.  Each test involves
//   transferring a buffer 2x --> host-to-DSP and DSP-to-host.
//   Each test also involves verifying the transfers.
//
// If NLOOPS == 0, then the tests will loop forever.

// Flag to indicate whether to use Windows Events (and WaitForSingleObject)
//   to wait for DSP-to-host transfers.  The alternative is to use busy-wait
//   loops.
