DAQmxGetExtendedErrorInfo
int32 DAQmxGetExtendedErrorInfo (char errorString[], uInt32 bufferSize);
Purpose
Returns dynamic, specific error information. This function is valid only for the last function that failed; additional NI-DAQmx calls may invalidate this information.
If you pass valid values for errorString and bufferSize, this function returns as much of the available data as possible.
If you pass NULL for errorString or 0 for bufferSize, this function returns the number of bytes you need to allocate.
