Iyisin, hossun da sistemde bir kere calistiktan sonra neden calismiyorsun hic anlamadim!

You are supposed to create 3 periodic tasks (using thread or fork mechanism, it’s up to you).
The period of these tasks are 1, 5 and 10 seconds. The job of the first task is to write “I am task
1” on the screen, for the second task “I am task 2” and so on. Since these tasks are periodic, for
example, the first task will repeatedly say “I am task 1” each second, similarly the other tasks
will periodically run and print their messages on the screen.

#include "stdio.h"
#include"signal.h"

void handler1(int sig)
{
 printf("I am task1");
 signal(sig, handler1);
}

void handler2(int sig)
{
 printf("I am task2");
 signal(sig, handler2);
}

void handler3(int sig)
{
 printf("I am task3");
 signal(sig, handler3);
}

int processFork(void *sighandler){

    int pid;

    if((pid = fork())== -1){
        printf("not forked!");
        exit(-1);
    }else if(pid == 0){
     printf("forked!\n");
        signal(SIGUSR1, sighandler);
        printf("signalled!\n");
  while(1)
  {
   sigpause(SIGUSR1);
   printf("duut\n");
  }
        exit(0);
    }

    return pid;

}

int main(void)
{
 int seconds;
 int process1, process2, process3;

        process1 = processFork(handler1);
 process2 = processFork(handler2);
 process3 = processFork(handler3);

 printf("process 1 : %d\n", process1);
 printf("process 2 : %d\n", process2);
 printf("process 3 : %d\n", process3);
 for(seconds = 0; seconds < 100; seconds++){
  if(seconds % 1 == 0){
   kill(process1, SIGUSR1);
  }
  if(seconds % 5 == 0){
   kill(process2, SIGUSR1);
  }
  if(seconds % 10 == 0){
   kill(process3, SIGUSR1);
  }
