annotate src/console.h @ 5602:c9e5612f5424
Support the MP library on recent FreeBSD, have it pass relevant tests.
src/ChangeLog addition:
2011-11-26 Aidan Kehoe <kehoea@parhasard.net>
* number-mp.c (bignum_to_string):
Don't overwrite the accumulator we've just set up for this
function.
* number-mp.c (BIGNUM_TO_TYPE):
mp_itom() doesn't necessarily do what this code used to think with
negative numbers, it can treat them as unsigned ints. Subtract
numbers from bignum_zero instead of multiplying them by -1 to
convert them to their negative equivalents.
* number-mp.c (bignum_to_int):
* number-mp.c (bignum_to_uint):
* number-mp.c (bignum_to_long):
* number-mp.c (bignum_to_ulong):
* number-mp.c (bignum_to_double):
Use the changed BIGNUM_TO_TYPE() in these functions.
* number-mp.c (bignum_ceil):
* number-mp.c (bignum_floor):
In these functions, be more careful about rounding to positive and
negative infinity, respectively. Don't use the sign of QUOTIENT
when working out out whether to add or subtract one, rather use
the sign QUOTIENT would have if arbitrary-precision division were
done.
* number-mp.h:
* number-mp.h (MP_GCD):
Wrap #include <mp.h> in BEGIN_C_DECLS/END_C_DECLS.
* number.c (Fbigfloat_get_precision):
* number.c (Fbigfloat_set_precision):
Don't attempt to call XBIGFLOAT_GET_PREC if this build doesn't
support big floats.

| 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 | |
