annotate src/fns.c @ 5255:b5611afbcc76
Support process plists, for greater GNU compatibility.
src/ChangeLog addition:
2010-09-02 Aidan Kehoe <kehoea@parhasard.net>
* process.c (process_getprop, process_putprop, process_remprop)
(process_plist, process_setplist, reinit_process_early):
Add functions to modify a process's property list.
* process-slots.h (MARKED_SLOT): Add a plist slot.
* fns.c (Fobject_setplist): New function, analogous to #'setplist,
but more general.
Update the documentation in the other plist functions to reflect
that processes now have property lists.
* emacs.c (main_1): Call reinit_process_early(), now processes have
plist methods that need to be initialised.
* symbols.c (reinit_symbol_objects_early): Fsetplist is the named
setplist method for symbols.
lisp/ChangeLog addition:
2010-09-02 Aidan Kehoe <kehoea@parhasard.net>
* obsolete.el (process-get):
Make #'process-get, #'process-put, #'process-plist,
#'set-process-plist available as aliases to the more general
functions #'get, #'put, #'object-plist, #'object-setplist, for GNU
compatibility.

| 570 As of XEmacs 21.0, this function does NOT accept individual integers | |
| 571 as arguments. Old code that relies on, for example, (concat "foo" 50) | |
| 572 returning "foo50" will fail. To fix such code, either apply | |
| 573 `int-to-string' to the integer argument, or use `format'. | |
