BBS Frontend for Daydream

ignatius333

I'm trying to write a front end of sorts for my BBS (Daydream BBS) in C. It has 4 options. (1) Show the PIDs of in.telnetd (2) Kill PID if applicable (3) "Snoop" a node and (4) Telnet to the BBS.

What I want to do, is allow option #1 to run in the foreground, in a window at the top of the screen, and be in real time, or, maybe even every 2 seconds, like what the command wait does. Is this possible? Here's the code I have so far:

// Ignatius' Daydream BBS frontend

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <ctype.h>
#include <signal.h>

#include <dirent.h>
#include <sys/types.h>
#include <unistd.h>
#include <ncurses.h>

/////////// variables /////////////////////////////

int group;

const int maxQuestionID = 4;
const int maxFileID = 10;

int cmdKey = 0;

int fileID = 0;
int questionID = 0;

/////////// end variables /////////////////////////
/////////// init function /////////////////////////

void init()
{

    printf("\e(U");
    initscr();
    cbreak();
    noecho();
    nonl();
    keypad(stdscr, TRUE);

}
///////////// main screen /////////////////////////

int main()
{

system("/usr/bin/clear");
init();
space();

}

 scanf("%d", &pid);

 killpid = kill(pid, SIGKILL);

 if(killpid == -1){
 printf("Termination failed!\n");
 return 0;
 }

 printf("Terminated process [%d]!", pid);
 return 0;
}

If someone could take a look at this, and, maybe point me in the right direction. I'd grately appreciate it.

Thanks.

Actually, I meant the watch command. Not wait
