SDgetfillvalue/sfgfill/sfgcfill

intn SDgetfillvalue(int32 sds_id, VOIDP fill_val)
sds_id

IN:

Dataset identifier returned from SDselect

fill_val

OUT:

Buffer for the returned fill value

Purpose

Reads the fill value for the given dataset if it exists.

Return value

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

Description

It is assumed that the data type of the fill value is the same as for the dataset.

Note that there are two Fortran-77 versions of this routine: sfgfill and sfgcfill. The sfgfill routine reads numeric fill value data and sfgcfill reads character fill value data.

FORTRAN

integer function sfgfill(sds_id, fill_val)

integer sds_id

<valid numeric data type> fill_val

integer function sfgcfill(sds_id, fill_val)

integer sds_id
