Create a process using fork() system call.

hey guys

here you can get the parallel processing basic

the first basic practical of the parallel processing is creating a process using fork system call


/* Create a process using fork() system call. */
#include <stdio.h>  
#include <sys/types.h>
#include <unistd.h>
#include <stdlib.h>
#include <errno.h>

int main(void)
{
   pid_t  pid;
      pid = fork();
   if (pid == -1)
   {  
      fprintf(stderr, "can't fork, error %d\n", errno);
      exit(EXIT_FAILURE);
   }

   if (pid == 0)
   {

      int j;
      for (j = 0; j < 10; j++)
      {
         printf("child: %d\n", j);
         sleep(1);
      }
      _exit(0);
   }
   else
   {
     
      int i;
      for (i = 0; i < 10; i++)
      {
         printf("parent: %d\n", i);
         sleep(1);
      }
      exit(0);
   }
   return 0;
}
