annotate src/console.h @ 5570:6c76f5b7e2e3
Be more careful still in #'cl-defsubst-expand.
lisp/ChangeLog addition:
2011-09-11 Aidan Kehoe <kehoea@parhasard.net>
* cl-macs.el (cl-defsubst-expand):
Be more careful still here, make sure that any references to
variables in BODY don't access those values in the enclosing scope
when that would be inappropriate.
Add some documentation of a potential reasonable approach to
avoiding the problems with our (non-Common Lisp-conformant)
#'symbol-macrolet.

| 26 /* Devices and consoles are similar entities. The idea is that | |
| 27 a console represents a physical keyboard/mouse/other-input-source | |
| 28 while a device represents a display where frames appear on. | |
| 3360 | 29 Nowadays "multi-headed" displays with multiple physical screens |
| 30 are becoming familiar; in the XEmacs nomenclature, this maps to a | |
| 31 "console" supporting multiple "devices". | |
| 32 | |
| 428 | 33 In the X world, a console is a "Display" while a device is a |
| 34 "Screen". Implementationally, it can sometimes get confusing: | |
| 35 under X, multiple devices on a single console are different | |
| 36 "Display" connections to what is in reality the same Display on | |
| 3360 | 37 the same server. Furthermore, in the X model input comes from the |
| 38 device and not from the console. This causes no confusion because | |
| 39 events are basically always tagged to a particular X window (i.e. | |
| 40 frame), which exists on only one screen; therefore the event won't | |
| 41 be reported multiple times even if there are multiple devices on | |
| 42 the same physical display. | |
| 43 | |
| 44 This is an implementation detail specific to X consoles (e.g. under | |
