Converts NDArray callback data into standard asyn arrays (asynInt8Array, asynInt16Array, asynInt32Array, asynFloat32Array or asynFloat64Array); normally used for putting NDArray data in EPICS waveform records.
It handles the data type conversion if the NDArray data type differs from the data type of the asyn interface. It flattens the NDArrays to a single dimension because asyn and EPICS do not support multi-dimensional arrays.

[in] | stackSize | The stack size for the asyn port driver thread if ASYN_CANBLOCK is set in asynFlags. |
