Yuck! Why do people make it hard for themselves ;-)

 void DAQmxErrChk( int(?) functionCall ) 
 {
   if (DAQmxFailed (error = functionCall))
      throw new DAQException("whatever");
 }

Then replace the 'Error:' label with ...

  scope(failure)
  {
    // Handle any exception thrown during this scope.
    if (error == ...) ...
  }
