3d0d5dccc1 Cast arg_max to size_t when comparing it (times 4, plus 1) against SIZE_MAX. I
was worried about truncation of arg_max by this cast, but if it gets truncated,
we know it'll obviously be greater than SIZE_MAX anyway.

05051e2898 Returning NULL here if malloc(3) fails is silly, at this point in the codepath
we have't malloc(3)'d nearly as much as we probably will, so errx(3) away,
instead of waiting for something to fail yet again later on.

86f54b9fb8 Remove an XXX comment that seems to be a tiny bit no longer pertinent. This
function seems to do the right thing, and is not a "stub", and whoever "marc"
is, he's had plenty of time to do "the real one", so don't wait around for
him any longer.

b69566d8e1 Use of zero here meant many things, NULL, '\0' (NUL), and 0. Sort it out. 2002-06-05 01:32:21 +00:00

634d96e194 Check for possible overflow from sysconf _SC_ARG_MAX and error out in a
correct manner.  Revert my incorrect change to use err(3) for malloc(3)
failing.  Use a size_t variable to store the size of the argument buffer
we allocate, and remove silly casts as the result of having this around.
Modify the math in some of the paranoid checks for buffer overflow to
account for the fact we now are dealing with the actual size of the
buffer.  Remove the static qualifier for arg_max, and the bogus setting
of it to -1.

Include <limits.h> for the definitions we use to check for possible
overflows.

3d674c947c Don't cast incorrectly to malloc(3), and don't use errx(3) if malloc(3)
returns NULL, as malloc(3) sets errno.  Use err(3).

871e8d8c59 WARNS=4 fixes (incomplete, so set NO_WERROR), and lots of extra
cleanup courtesy of automatic checking (lint).

46251dde8f o __P has been reoved
o Old-style K&R declarations have been converted to new C89 style
o register has been removed
o prototype for main() has been removed (gcc3 makes it an error)
o int main(int argc, char *argv[]) is the preferred main definition.
o Attempt to not break style(9) conformance for declarations more than
  they already are.

1130b656e5 Make the long-awaited change from $Id$ to $FreeBSD$
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.

fa49dc9cf0 Fix an error to prevent some core dumps from ps.
You can get ps easily to core dump, if you are running a "make depend"
on a kernel in one window and a "ps -auxww" in another. The ww will
try to give you the full argument list of the command that can
now be 64Kb large, but ps expected only 4Kb large arg arrays and
doesn't check for overflows.
