Description
|
SDgetinfo retrieves the name, number of dimensions, sizes of dimensions, data type, and number of attributes of the data set identified by sds_id, and stores them in the parameters sds_name, rank, dimsizes, data_type, and num_attrs, respectively.

|
If the data set is created with an unlimited dimension, then in the C interface, the first element of the dimsizes array (corresponding to the slowest-changing dimension) contains the number of records in the unlimited dimension; in the FORTRAN-77 interface, the last element of the dimsizes array (corresponding to the slowest-changing dimension) contains this information. Use SDisrecord to determine if the data set has an unlimited dimension.
