I've been meaning to do this for AGES as I keep having to patch those routines
whenever I write a proprietary package or similar..
any module that assigns resources to processes needs to know when
these events occur. there are existsing modules that should be modified
to take advantage of these.. e.g. SYSV IPC primatives
presently have #ifdef entries in exit()
this also helps with making LKMs out of such things..
(see the man pages at_exit(9) and at_fork(9))
so that people can look and comment.
I'll add the at_fork and at_exit immediatly, but I'll
add teh at_shutdown later as it's more extensive
and I desire people's comments..
julian
called kern_shutdown.c
note: I couldn't see anything machine dependant in the
functions boot() and dumpsys() which were in machdep.c
I have left a prototype for cpu_boot() which would go in
machdep.c, but I have nothing to put in it. Iexpect others will
let me know in no uncertain ways that this or that is machine dependant
and should be there, but I'll way for that to happen.. :)
I haven't actually taken the functions OUT of machdep
or anywhere else yet.. I'm checking in this file so others can have a look
at it and comment. SO PLEASE DO COMMENT!
I am also (in another checkin) addinf a man(9) page for the new
at_shotdown().. er freudian slip there.. at_shutdown() call
so have a look at that (and at_exit and at_fork as well)
and feed me comments..
I'll heck in the changes to make these (shutdown) changes active tomorrow
if no-one objects too strongly..
gcc-2.7 has __attribute__((unused)) as a postfix operator on function
arguments to prevent -Wunused from complaining about them. gcc < 2.7
doesn't have anything like this (and doesn't care about it either).
eg:
int foo(bar, baz)
int bar __unused; /* needed because of function pointer typing */
char *baz __unused;
{
return (1);
}
- inet_ntoa() returns a pointer to a static buffer, dont use it twice
in the same printf().
- prevent the possibility of never timing out
- Report two more ICMP error types (prohibited nets etc)
And some (commented out) enhancements that I use, but some don't like.
bombing mercilessly.
(2) If that directory has a directory called CVS, remind the user of
the existence of the "-P" option to cvs co and update.
(3) While I'm here, clean up the PATCH_DEBUG code a bit. In
particular, don't duplicate a whole bunch of code just for adding
a single "echo" statement. ;)

editor safer. The old one was too deadly, if the blank line after the
"FreeBSD" version banner was missing, it would delete from the beginning
of the file up until the next blank line, possibly to the end of file.
This was not good.

during phk's staticize/cleanup commits. pstat needs it, the MAXCONS
option is not visible anywhere else, and pstat uses it to find the bounds
of the sccons[MAXCONS] array, which varies.
I was perplexed when an example I'd written to show the values for these
variables changing as an xterm window was resized didn't work, and looking
into it I see that size tracking for LINES and COLS seems to be one SVR4
enhancement which didn't come across with libncurses.
