the stdio buffer.

1fd98d7d88 Calls one or more of malloc(), warn(), err(), syslog(), execlp() or
execvp() in the child branch of a vfork(). Changed to use fork()
instead.

Some of these (mv, find, apply, xargs) might benefit greatly from
being rewritten to use vfork() properly.

50cc4492c6 Alpha support for truss. I tested this on both bento and beast (thanks,
Jordan, for pointing me at beast!).  There should be no change for the
i386 version.

3625b5147c Use a default execution type if none of the listed ones match. This
uses the first type listed in the array as the default type.  This isn't
perfect, but I thought it would be better than nothing.

19db2a3c0b Proper way to do the previous mis-commit. Still not quite right, because
some header files (e.g., <err.h>) include <machine/something.h>, and this
will not pick up the right header files, so it may be removed eventually
anyway.  But some people who are not willing to build the right way
apparantly want this, so this is for them.

41ccb63223 Get rid of the bogus include -- it is incomplete (as it doesn't handle
anything other than <sys/*.h>), and unnecessary in most cases.  (The
situations where it is necesary can be dealt with by manually-made symlinks,
which is acceptable since they should only occur during testing.  Remember:
the tree does not compile well if you do not have matching header files
installed.  Half-baked -I directives don't cover enough of the cases.)

3cf51049e0 Sort Xrefs. Use err(3). Remove uneeded #include.
Correct usage: one of {-p pid, command} is required.
Open output file when command line is fully analyzed: incorrect `truss -o f'
command does not create an empty file anymore.

09d64da3a4 Add some copyright and license terms, at Jordan's request. Note that
syscall.h just refers to another file for the copyright notice.

d7b7dcba41 Change the ioctls for procfs around a bit; in particular, whever possible,
change from

	ioctl(fd, PIOC<foo>, &i);

to

	ioctl(fd, PIOC<foo>, i);

This is going from the _IOW to _IO ioctl macro.  The kernel, procctl, and
truss must be in synch for it all to work (not doing so will get errors about
inappropriate ioctl's, fortunately).  Hopefully I didn't forget anything :).

20fa828fac Use the new PF_LINGER flag -- when this is set in a process' proc structure,
said process will not have its event mask cleared (and be restarted) on
the last close of a procfs/mem file for that pid.  This reduces the chance
that a truss-monitored process will be left hanging with these bits set
and nobody looking for it.

This is the least-tested change of all of these, I'm afraid.

970649f9c9 First cut at printing out ioctl names intelligently. Note that this doesn't
handle linux ioctls (yet?).  This uses the mkioctl script from kdump,
bless its little heart.
