=head1 NAME
Proc::ProcessTable::Process - Perl process objects
=head1 SYNOPSIS
$process->kill(9);
$process->priority(19);
$process->pgrp(500);
$uid = $process->uid;
...
=head1 DESCRIPTION
This is a stub module to provide OO process attribute access for
Proc::ProcessTable. Proc::ProcessTable::Process objects are
constructed directly by Proc::ProcessTable; there is no constructor
method, only accessors.
=head1 METHODS
=over 4
=item kill
Sends a signal to the process; just an aesthetic wrapper for perl's
kill. Takes the signal (name or number) as an argument. Returns number
of processes signalled.
=item priority
Get/set accessor; if called with a numeric argument, attempts to reset
the process's priority to that number using perl's <B>setpriority
function. Returns the process priority.
=item pgrp
Same as above for the process group.
=item all other methods...
are simple accessors that retrieve the process attributes for which
they are named. Currently supported are:
uid UID of process
gid GID of process
euid effective UID of process (Solaris only)
egid effective GID of process (Solaris only)
pid process ID
ppid parent process ID
spid sprod ID (IRIX only)
pgrp process group
sess session ID
cpuid CPU ID of processor running on (IRIX only)
priority priority of process
ttynum tty number of process
flags flags of process
minflt minor page faults (Linux only)
cminflt child minor page faults (Linux only)
majflt major page faults (Linux only)
cmajflt child major page faults (Linux only)
utime user mode time (1/100s of seconds) (Linux only)
stime kernel mode time (Linux only)
cutime child utime (Linux only)
cstime child stime (Linux only)
time user + system time
ctime child user + system time
timensec user + system nanoseconds part (Solaris only)
ctimensec child user + system nanoseconds (Solaris only)
qtime cumulative cpu time (IRIX only)
size virtual memory size (bytes)
rss resident set size (bytes)
wchan address of current system call
fname file name
start start time (seconds since the epoch)
pctcpu percent cpu used since process started
state state of process
pctmem percent memory
cmndline full command line of process
ttydev path of process's tty
clname scheduling class name (IRIX only)

up-to-date information.
