Необходимо добавить
#include <unistd.h>
использовать fork, измените все “ кому: " и добавьте закрытие } в конце:
#include<stdio.h>
#include<sys/wait.h>
#include <unistd.h>
int main()
{
int p1,p2;
p1=fork();
if(p1==-1)
{
printf("Error");
}
else
{
printf("Parent is %d, Child is %d n",getppid(),getpid());
}
p2=fork();
printf("Parent is %d, Child is %d n",getppid(),getpid());
return 0;
}
