in termios.h, but it's prototype in termcap.h and the main file use
the underlying definition (which is now an int, not a long for
compatibility with NetBSD). Really termcap.h should use speed_t too,
but I guess that this might break sources that don't include termios.h
first.
unsigned integral type. Changing it doesn't seem to cause any
sign extension bugs in /usr/src. In the kernel, this is partly
because `struct speedtab' and its lookup function are too bogus
to use speed_t's for speeds - they use ints.

where shared libraries are in /lib and almost everything is linked
shared. First, they removed the old shared library before installing
the new one. Second, they attemped a cross-device link from /lib
to /usr/lib/compat.
to the same version numbers as 2.2.x.
The problem with the way things were was:
- if you took a 2.2.x binary, it either wouldn't run on -current or
if you had the old -current version of libtermcap.so.2.1 then it could
potentially be a security problem.
- the alternative is to start a compat22 tree dist for -current with a
uuencoded binary. This makefile hack is less cost.
libtermcap.so.3.0 is provided via /usr/lib/compat to avoid transition
problems.
a similar way to libc. Sigh. This is not pretty but seems to work.
Somthing like this was needed in preference to bogusly bumping the major
library number here.
The syscall(SYS_issetugid) idea is originally Bruce's.
`void __set_ospeed(long);' in the appropriate header.
The implementation still uses speed_t instead of long. This
will break properly when speed_t is fixed (speed_t shall be
unsigned ...).
This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.
Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.
conflict with the other declarations in other files. tputs() is
traditionally declared to return int, not void. curses.h has it as int.
ncurses has int and actually sets the return value. This problem has
been causing the ircII port to not compile.
(I've only minimally tested this, I do not have libtermcap on my systems)
specified in the top level Makefiles.
Previously I missed dozens of Makefiles that skip the install after
using `cmp -s' to decide that the install isn't necessary.
variable directly in tgetent by stderr or stdout output speed.
It helps hide in non-standard __set_ospeed function and remove it
from other sources (coming soon).
Do prototype cleanup too.
Basically all termios+termcap pgms needs it.
It set ospeed variable using nearest-matched stty speeds,
which helps termcap pgms works with non-fixed termios speeds
and not duplicate ospeed switch into every pgm.
Also it isn't standard function, its source code is too big to include it
in whole to every termcap+termios pgm.
1) Eliminate spaces and double ':'.
2) Remove duplicated capabilities from tc= expansion.
It is needed to not overflow historycal 1024 limit.
Add range check and return -1 if entry is too big instead
of corrupting user memory.
Change the reference for the libtermcap libtermlib link from SHLIBDIR
to LIBDIR. SHLIBDIR is undefined in the standard case.
termcap.c:
Initialize a local variable to zero. Otherwise an erroneous free call
can happen and clobber the calling program.
Seen with vi and gdb. If you have TERMCAP set with a terminal entry and
set TERM with something like huhu, vi and gdb core dumps.
on terminals with no pad char (cons25) and quote from tputs.c says so too:
! * Too bad there are no user program accessible programmed delays.
! * Transmitting pad characters slows many
! * terminals down and also loads the system.
