Description

If the values of rank or dimsizes aren't known, DFSDgetdims must be called to retrieve them and then use them to determine the buffer space needed for the array data. If the data type of the data in a scientific dataset isn't know, DFSDgetNT must be called to retrieve it. Subsequent calls to DFSDgetdata (or to DFSDgetdims and DFSDgetdata)will sequentially read scientific datasets from the file. For example, if DFSDgetdata is called three times in succession, the third call reads data from the third scientific dataset in the file.
