DFSDgetNT/dsgnt

intn DFSDgetNT(int32 *data_type)
data_type

OUT:

Data type of data in the scientific dataset

Purpose

Retrieves the data type of the next dataset to be read.

Return value

Returns SUCCEED (or 0) if successful and FAIL (or -1) otherwise.

Description

Note that DFSDgetNT does not take a file name as an argument. As a result, a DFSD call to initialize the file information structures is required before calling DFSDgetNT. One such call is DFSDgetdims.

Valid values for data_type are of the general form DFNT_. The following are valid symbolic names and their data types:

32-bit float DFNT_FLOAT32 5
64-bit float DFNT_FLOAT64 6
8-bit signed int DFNT_INT8 20
8-bit unsigned int DFNT_UINT8 21
16-bit signed int DFNT_INT16 22
16-bit unsigned int DFNT_UINT16 23
32-bit signed int DFNT_INT32 24
32-bit unsigned int DFNT_UINT32 25
8-bit character DFNT_CHAR8 4
FORTRAN

integer function dsgnt(num_type)
