DAQmxGetErrorString
int32 DAQmxGetErrorString (int32 errorCode, char errorString[], uInt32 bufferSize);
Purpose
Converts the error number returned by an NI-DAQmx function into a meaningful error message.
If you pass in a valid value for errorString and its 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.

|---|---|---|
| errorCode | int32 | An error code or warning returned by one of the NI-DAQmx Library functions. |
| bufferSize | uInt32 | The size, in bytes, of the buffer passed in the errorString. If you pass 0, this function returns the number of bytes you need to allocate. |

The meaningful error message for the error number. If you pass NULL, this function returns the number of bytes you need to allocate. |

| status | int32 | The error code returned by the function in the event of an error or warning. A value of 0 indicates success. A negative value indicates an error. If you pass in a valid value for errorString and its 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. |
