Great thanks. Let me try this, if things work fine, I'll put my working code here for others to learn.

---------- Post updated at 10:56 PM ---------- Previous update was at 10:49 PM ----------

Hello, Alister,
There are several machines in my computing laboratory some of which are 64 bit machines and others 32 bit. I do not have a fixed machine to work on, so sometimes I may use 64bit machine and sometimes 32bit. Just to keep my code portable, I use int32_t.

But now I am curious to know. Is my logic described in the above paragraph correct? Or I am fundamentally mistaken about the machine architectures and the way I use int32_t?

rwho

RWHO(1) 						    BSD General Commands Manual 						   RWHO(1)

NAME

     rwho -- who is logged in on local machines

SYNOPSIS

     rwho [-a]

DESCRIPTION

     The rwho command produces output similar to who, but for all machines on the local network.  If no report has been received from a machine
     for 11 minutes then rwho assumes the machine is down, and does not report users last known to be logged into that machine.

     If a users hasn't typed to the system for a minute or more, then rwho reports this idle time.  If a user hasn't typed to the system for an
     hour or more, then the user will be omitted from the output of rwho unless the -a flag is given.

FILES

     /var/spool/rwho/whod.*   information about other machines

SEE ALSO

     finger(1), rup(1), ruptime(1), rusers(1), who(1), rwhod(8)

HISTORY

     The rwho command appeared in 4.3BSD.

BUGS

     This is unwieldy when the number of machines on the local net is large.
