GRattrinfo/mgatinf

int32 GRattrinfo(int32 [ri, gr]_id, int32 attr_index, char *name, int32 *data_type, int32 *length)

[ri, gr]_id	IN:	Raster image or GR dataset identifier of the target object
attr_index	IN:	Index of the attribute
name	OUT:	Buffer for the name of the attribute
data_type	OUT:	Data type of the attribute
length	OUT:	Length of the attribute

Purpose	Reads the specified attribute's data type and length.
Return value	Returns SUCCEED (or 0) if successful and FAIL (or -1) otherwise.
Example	This example illustrates the use of GRattrinfo in reading the attributes of a general raster image:

     #include "hdf.h"

     int32 ri_id, gr_id, stat, attr_index;
      int32 *data_type, length;
      int32 attr_values[2];
      char name[MAX_GR_NAME];
        ...
      ri_id = GRselect(gr_id, 0);
      stat = GRattrinfo(gr_id, attr_index, name, data_type,
           length);
      stat = GRgetattr(ri_id, attr_index, attr_values)
       ...
