displayed to users. These are Lisp_Save_Value, a Lisp_Misc
subtype; and PVEC_OTHER, a kind of vectorlike object. The former
is suitable for temporarily stashing away pointers and integers in
- a Lisp object (see the existing uses of make_save_value and
- XSAVE_VALUE). The latter is useful for vector-like Lisp objects
+ a Lisp object. The latter is useful for vector-like Lisp objects
that need to be used as part of other objects, but which are never
shown to users or Lisp code (search for PVEC_OTHER in xterm.c for
an example).

This is mostly used to package C integers and pointers to call
record_unwind_protect when two or more values need to be saved.
- make_save_value lets you pack up to SAVE_VALUE_SLOTS integers, pointers,
- function pointers or Lisp_Objects and conveniently get them back
- with XSAVE_INTEGER, XSAVE_POINTER, XSAVE_FUNCPOINTER, and
- XSAVE_OBJECT macros:
+ For example:
...
struct my_data *md = get_my_data ();
- Lisp_Object my_object = get_my_object ();
- record_unwind_protect
- (my_unwind, make_save_value (SAVE_TYPE_PTR_OBJ, md, my_object));
+ ptrdiff_t mi = get_my_integer ();
+ record_unwind_protect (my_unwind, make_save_ptr_int (md, mi));
...
Lisp_Object my_unwind (Lisp_Object arg)
{
struct my_data *md = XSAVE_POINTER (arg, 0);
- Lisp_Object my_object = XSAVE_OBJECT (arg, 1);
+ ptrdiff_t mi = XSAVE_INTEGER (arg, 1);
...
}
If ENABLE_CHECKING is in effect, XSAVE_xxx macros do type checking of the
saved objects and raise eassert if type of the saved object doesn't match
the type which is extracted. In the example above, XSAVE_INTEGER (arg, 2)
- or XSAVE_OBJECT (arg, 0) are wrong because nothing was saved in slot 2 and
- Lisp_Object was saved in slot 1 of ARG. */
+ and XSAVE_OBJECT (arg, 0) are wrong because nothing was saved in slot 2 and
+ slot 0 is a pointer. */
