967706f308 Check if name is NULL before we strcmp the syscall name. This was 
sometimes triggered if you began trussing a process while it was
in a syscall, as the name is filled in when the syscall is made.

1d631f7ef1 Don't depend on <signal.h> to include <sys/time.h>, instead include 
<sys/time.h> directly.  This is mostly bogus since CLOCK_REALTIME
should be defined in <time.h>, which these files already include.

9897b20356 Add options to print the argument and environment string parameters to 
execve().

This could be done in a more general manner but it still wouldn't
be very pretty.

7c8225cab8 Use fseeko and uintptr_t to make sure that we get a sensible offset

dec17687ad Add missing include for <ctype.h> 
Make sockaddr printing code unbad.

Always copy in sizeof(sockaddr_un) bytes for an AF_UNIX sockaddr,
despite what the length may be.

9ddd141263 Teach truss(1) to display sockaddrs. It currently knows about AF_INET, 
AF_INET6 and AF_UNIX sockaddrs, and will recognize accept(), bind(),
connect(), getpeername() and getsockname() as syscalls taking sockaddr
arguments.  Some enterprising soul might want to add (and test) support
for the send() / recv() family of syscalls as well.

8a2ecea916 In get_string(), 0-terminate the contents of buf ``just in case''; 
otherwise, if the very first fgetc() already yielded EOF, the returned
string won't get terminated at all.

6cb533fe1c Change the output of truss to more closely resemble SysV's. (Yes, it 
really is much nicer looking.)

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.

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.
