In Mac OS X 10.4 Tiger, iChat lets you audio conference with up to nine additional people and video conference with up to three additional people. Here are the system requirements you need to initiate or participate in audio and video chats and conferences in iChat.
Does anyone know the system requirements for Unix 03? I need the CPU, RAM, and harddisk space requirements. I have been looking all over the web but can't seem to find the numbers. If you could post a link that would be great. Thanks (0 Replies)

people(2) System Calls Manual people(2)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... */
}
}
