/*-------------------------------------------------------------------------
 * Purpose:	Register function entry for library initialization and code
 *		profiling.
 *
 * Notes:	Every file must have a file-scope variable called
 *		`initialize_interface_g' of type hbool_t which is initialized
 *		to FALSE.
 *
 *		Don't use local variable initializers which contain
 *		calls to other library functions since the initializer
 *		would happen before the FUNC_ENTER() gets called.  Don't
 *		use initializers that require special cleanup code to
 *		execute if FUNC_ENTER() fails since a failing FUNC_ENTER()
 *		returns immediately without branching to the `done' label.
 *
 * Programmer:	Quincey Koziol
 *
 * Modifications:
 *
 *	Robb Matzke, 4 Aug 1997
 *	The `interface_init_func' can be the null pointer.  Changed
 *	HGOTO_ERROR() to HRETURN_ERROR() since no clean-up needs to occur
 *	when an error is detected at this point since this must be the
 *	first executable statement in a function.  This allows functions
 *	to omit the `done:' label when convenient to do so.
 *
 *	Robb Matzke, 4 Aug 1997
 *	The pablo mask comes from the constant PABLO_MASK defined on
 *	a per-file basis.  The `pablo_func_id' is generated from the
 *	`func_name' argument by prepending an `ID_' to the name.  The
 *	pablo function identifier should be saved in a local variable
 *	so FUNC_LEAVE() can access it.
 *
 *	Robb Matzke, 4 Aug 1997
 *	It is safe to call this function even inside various library
 *	initializing functions.	 Infinite recursion is no longer a
 *	danger.
 *
 *	Robb Matzke, 3 Dec 1997
 *	The interface initialization function is no longer passed as an
 *	argument unless the `FUNC_ENTER_INIT' form is called.  Instead, the
 *	function comes from the `INTERFACE_INIT' constant which must be
 *	defined in every source file.
 *
 *	Robb Matzke, 17 Jun 1998
 *	Added auto variable RTYPE which is initialized by the tracing macros.
