// I'm sorry.

switch(value)
{
   [...]
default:
   ASSERT(**true**); // if this is triggered, something really bad is happening.
}

场景一:

return 0; // Happy ending

场景二:

int32_t Interpolate1DSignal(
  Array1D<float64>::Handle hfInputSamples,         // samples to be interpolated
  Array1D<float64>::Handle hfInterpolationFilter,  // polyphase filter coefficients,
  int32_t iFilterInterpolationFactor,              // # of "rows" in polyphase filter
  int32_t iFilterLength,                           // Length of each row in filter
  float64 fInterpolationFactor,                    // Factor to interpolate the
                                                   // signal by
  float64 fTimingOffset,                           // Offset into the signal (units   
                                                   // of samples)
  Array1D<float64>::Handle hfOutputSamples         // left as an exercise for the reader
);

我没有亲身经历过这种情况，但这是一个很好的故事(详见我的评论中的解释):

#define MSGTAG_B33R     0x723 /* RIPLVB */

// set break point here - you'll never reach it
