 *          The configuration constants like H5_HAVE_UNISTD_H etc. are
 *          defined in H5config.h which is included by H5public.h.

/*-------------------------------------------------------------------------
 * 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.
 *
 *    Quincey Koziol, 28 May 2002
 *    Split FUNC_ENTER macro into FUNC_ENTER_API, FUNC_ENTER_NOAPI and
 *      FUNC_ENTER_NOAPI_NOINIT.
