You can try to declare main with arguments;

int main(int argc, char *argv[])

This program was used in an application, where a PC was controlling critical tasks. Lets call it PC_critical. Unfortunately, PC_critical occasionally stalled and had to be manually reset.

Thus, a second PC (PC_monitor) was used. PC_critical was to send a message to PC_monitor every five minutes to assure that it was "alive". If no message was received, PC_monitor forced a hard reset of PC_critical by applying a momentary relay closure across the manual reset switch on PC_critical. The operation of the relay was caused by outputting the pattern 0x0a on the Data Port.

You can try this as an example.

Code:
#include <stdio.h>
#include <conio.h>
#include <dos.h>
#include <process.h>

int main(int argc, char *argv[])
{
   unsigned int t_delay, Data;
   int tenths_sec;

   clrscr();

   if(argc != 3)
   {
      printf("Incorrect number of args\n");
      exit(-1);
   }
   if(sscanf(argv[1],"%d", &tenths_sec)!=1)
   {
      printf("Time scanf failed.\n");
      exit(-2);
   }
   if (sscanf(argv[2],"%x", &Data) != 1)
   {
      printf("Parallel port scanf failed.\n");
      exit(-3);
   }
   t_delay = tenths_sec * 100;
   outportb(Data, 0x0a); /* operate the relay */
   delay(t_delay);
   outportb(Data, 0x00); /* release it */
   exit(0);
}

ICLINGO(1)						      General Commands Manual							ICLINGO(1)

NAME

       iclingo - an incremental ASP system

SYNOPSIS

       iclingo [options][files]

DESCRIPTION

       This manual page documents briefly the iclingo command.

       iclingo	is  an	incremental  ASP  system implemented on top of clingo. It is based on the idea that the grounder as well as the solver are
       implemented in a stateful way. Thus, both keep their previous states while increasing an incremental parameter. As  regards  grounding,	at
       each  incremental  step,  the  goal  is to produce only ground rules stemming from the current program slice, without re-producing previous
       ground rules. The ground program slices are then gradually passed to the solver that accumulates ground rules and computes answer sets  for
       them.

OPTIONS

       These  programs	follow	the  usual  GNU  command  line	syntax, with long options starting with two dashes (`-').  A summary of options is
       included below.	For a complete description, see the potassco-guide.

       -h, --help
	      Show summary of options.

       -v, --version
	      Show version of program.
