background running process

elbriga · 09-21-2004, 05:18 PM

Hi all,

Im new to linux programming, but I have a lot of experience in C...
Im connecting an LCD display (that ones with 2 lines and 16 cols...) on the parallel port, and I know how to control it ok. I want it to show system status of all kinds... and also I have some buttons atached to the LPT to send some commands...
Can someone give me some pointer, tutorials on how to make my program run as a process on background?

Thanks already, Gabriel

Code:

/* Jump into background */
  if(fork())
    exit(0);
  setpgrp();
