Use the TDMS Advanced Data Reference I/O functions to interact with data that is owned by a component external to LabVIEW, such as the direct memory access (DMA) buffer of a device driver that controls a data-streaming device. You can use these functions to asynchronously write data from the DMA buffer of a device driver to .tdms files without needing to copy the data into a LabVIEW array first. You also can use these functions to asynchronously read data from .tdms files and place the data directly into the DMA buffer.

Note To use the TDMS Advanced Data Reference I/O functions, you must set the enable asynchronous? input of the TDMS Advanced Open function to TRUE.
