Synopsis:
$pid()
$ppid()
Technical:
This pair of functions return the client's current Unix process id, and
its parent's process id, respectively.
Practical:
These functions don't have much practical value. One possible use might
be to add a CTCP command that returns their values, allowing one to
remotely kill a client that is responsive on the network, but not from
the keyboard.
Returns:
client process's pid/ppid
