file_id

IN:

File identifier returned by Hopen

	Purpose	Closes the access path to the file.
	Return value	Returns SUCCEED (or 0) if successful and FAIL (or -1) otherwise.
	Description	The file identifier file_id is validated before the file is closed. If the identifier is valid, the function closes the access path to the file.
		If there are still access identifiers attached to the file, the error DFE_OPENAID is placed on the error stack, FAIL (or -1) is returned, and the file remains open. This is a common error when developing new interfaces. Refer to the Reference Manual page on Hendaccess for a discussion of this problem.

	FORTRAN	integer function hclose(file_id)
