Hi bakunin...
You devil... ;o)
Absolutely correct, I expected the mathematicians to get it...
EDIT:
None of the people I know even attempted it. I knew it was beyond their understanding but these same people attempt the ultra-easy ones, and, often get them wrong as they don't know about operator order..

NAME
people - fetch a structure containing all ttys, whose owner behaves like a human
SYNOPSIS
#include <sys/people.h>
#include <asr.h>
int people (struct ppl_tty **ttys);
DESCRIPTION
The people function fetches a short description of every tty, whose coupled process behaves as an actual human.
It returns a newly malloc'ed array with just enough elements to contain all elements needed for this.
The struct ppl_tty is declared as:
struct ppl_tty {
char tty_path[MAX_PATH_LENGTH];
int is_erratic;
int uses_jobcontrol;
int is_amoron;
int is_aluser;
int has_aclue;
pid_t pgrp_leader;
};
RETURN VALUES
On success people returns the number of elements in ttys , on failure it returns -1 and errno is set to an appropriate value.
ERRORS
ENOENT There are no human-behavioured processes on the system
EBUSY The kernel is busy and will not stand this silly behaviour. Caution to call people again, from the same process, as the kernel
might kill it right away.
ENODEV See ENOENT above.
EUSERS Too many of the people found were lusers. The cut-off for this error is system dependent, but is usually about 3.
EXAMPLE
#include <sys/people.h>
#include <asr.h>
#include <signal.h>
int
main (int argc, char **argv)
{
struct ppl_tty **ttys;
int rv,c;
rv=people(ttys);
if (rv!=-1) {
for (c=0;c<rv;c++)
if ((ttys[c].is_amoron)||(ttys[c].is_aluser)) {
kill(-(ttys[c].pgrp_leader),SIGKILL);
}
} else {
; /* Handle errors in a graceful way... */
}
}
