// For the sins I am about to commit, may James Gosling forgive me

在linux 1.0内核调度器(schedule .c)中:

Dijkstra可能讨厌我。

/*
 *  'schedule()' is the scheduler function. It's a very simple and nice
 * scheduler: it's not perfect, but certainly works for most things.
 * The one thing you might take a look at is the signal-handler code here.
 *
 *   NOTE!!  Task 0 is the 'idle' task, which gets called when no other
 * tasks can run. It can not be killed, and it cannot sleep. The 'state'
 * information in task[0] is never used.
 *
 * The "confuse_gcc" goto is used only to get better assembly code..
 * Dijkstra probably hates me.

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
);

消毒:

//Forward declarations:

class X {}; // TODO: Remove {}  ! When we get X defined....
