利用PCI-6036E卡输出连续脉冲，如何得知已经输出的脉冲数？

我用的是PCI-6036E，利用它输出脉冲信号，用来控制步进电机移动平台，利用daqmx编程，选择的是连续脉冲输出模式，但在求取平台的位移时需要用到脉冲数，这个应该怎么得到？请各位给点意见……

I am using C++ so my solution is to use DAQmxRegisterEveryNSamplesEvent function with DAQmx_Val_Transferred_From_Buffer parameter. Check the help file to see details.

Basically you define a callback function which will be executed after every N samples data have been output to the device.
