sd_id

IN:

SD interface identifier returned by SDstart

	Purpose	Terminates access to an SD interface.
	Return value	Returns SUCCEED (or 0) if successful and FAIL (or -1) otherwise.
	Description	SDend closes the file and frees memory allocated by the library when SD interface activities are completed. If the calling program exits without invoking this routine, recent changes made to the in-core file data are likely not to be flushed to the file. Note that each SDstart must have a matching SDend.

	FORTRAN	integer function sfend(sd_id)
		integer sd_id
