getting certain info for all processes currently running

i am writing a utility that displays information about all the running processes in the /proc directory.

I do not know how to get the following information for each of the processes in the /proc directory:

-effective user id
-effective user name
-effective group id
-effective group name
-tty
-execution time of process

I understand how to get the user id. It is from the stat struct. And to get the user name, I just pass the user id to getpwuid(). Its the same with the group id and group name.

But I''m stuck at where I can obtain the effective user id and effective group id and how to get their effective names.

Also, where can i obtain information about which terminal the current process is being controlled by? It should be in the form "/pts/#"

Also, how can i find out how long a process has been executing?

Thank you.

killall5

KILLALL5(8)						Linux System Administrator's Manual					       KILLALL5(8)

NAME

       killall5 -- send a signal to all processes.

SYNOPSIS

       killall5 -signalnumber [-o omitpid[,omitpid..]]	[-o omitpid[,omitpid..]..]

DESCRIPTION

       killall5  is the SystemV killall command. It sends a signal to all processes except kernel threads and the processes in its own session, so
       it won't kill the shell that is running the script it was called from. Its primary (only) use is in the rc scripts found in the /etc/init.d
       directory.

OPTIONS

       -o omitpid
	      Tells killall5 to omit processes with that process id.

NOTES

       killall5 can also be invoked as pidof, which is simply a (symbolic) link to the killall5 program.

EXIT STATUS

       The  program  return  zero  if  it  killed  processes.  It return 2 if no process were killed, and 1 if it was unable to find any processes
       (/proc/ is missing).

SEE ALSO

       halt(8), reboot(8), pidof(8)
