Write a C Program to simulate process synchronization, call wait function so that the executing process gets blocked and then print their process ids before and after calling wait

Code for Program to simulate process synchronization, call wait function so that the executing process gets blocked and then print their process ids in C Programming

int main()
{
        int i,pid;

        printf("pid : %d \n",pid);

        pid=fork();

        printf("pid : %d \n",pid);

        printf("\n");

        if(pid==0)
        {
                printf("Child starts\n");

                for(i=0;i<5;i++)
                {
                        printf("i : %d\n",i);
                        printf("\n");
                }
                printf("Child ends\n");
        }
        else
        {
                printf("\nBefore wait\n");
                printf("getpid : %d\n",getpid());
                pid=wait(0);
                printf("\npid : %d\n",pid);
                printf("After wait\n");
                printf("Parent\n");
                printf("getpid : %d\n",getpid());
        }
}



















Output:

[04mca8@LINTEL pp]$ ./a.out
pid : 8884256
pid : 0

Child starts
i : 0

i : 1

i : 2

i : 3

i : 4

Child ends
pid : 23325


Before wait
getpid : 23324

pid : 23325
After wait
Parent
getpid : 23324
