MrRissso [65]

Answer:

Complete code is given below:

Explanation:

#include <stdio.h>

#include <sys/types.h>

#include <unistd.h>

#include <time.h>

#include <sys/wait.h>

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

pid_t mypid, childpid;

int status;

int i,n;

time_t t;

     

mypid = getpid();

printf("pid is %d.\n", mypid);

childpid = fork();

if ( childpid == -1 ) {

perror("Cannot proceed. fork() error");

return 1;

}

 

 

if (childpid == 0) {

 

 

mypid = getpid();

 

 

childpid = fork();

if ( childpid == -1 ) {

perror("Cannot proceed. fork() error");

return 1;

}

 

if (childpid == 0) {

 

mypid = getpid();

printf("Child pid is %d.\n", getppid());

 

childpid = fork();

 

 

if ( childpid == -1 ) {

perror("Cannot proceed. fork() error");

return 1;

}

random((unsigned) time(&t));

printf(" parent id = %d : Random = %d\n",mypid , (int)(random()% 100 +1));

printf("child id = %d : Random = %d\n",getpid , (int)(random()% 100 +1));

 

if (childpid == 0) {

 

printf("Child 2: I hinerited my parent's PID as %d.\n", mypid);

 

mypid = getpid();

printf("Child 2: getppid() tells my parent is %d. My own pid instead is %d.\n", getppid(), mypid);

 

sleep(30);

return 12;

} else return 15;

} else {

 

while ( waitpid(childpid, &status,0) == 0 ) sleep(1);

 

if ( WIFEXITED(status) ) printf("Child 1 exited with exit status %d.\n", WEXITSTATUS(status));

else printf("Child 1: child has not terminated correctly.\n");

}

} else {

printf(" fork() is ok and child pid is %d\n", childpid);

wait(&status);

 

if ( WIFEXITED(status) ) printf(" child has exited with status %d.\n", WEXITSTATUS(status));

else printf(" child has not terminated normally.\n");

}

 

return 0;

}

Output:

pid is 24503.

Child   pid  is 24565.

parent id = 24566 : Random = 87

child id = 1849900480 : Random = 78

pid is 24503.

Child 1  exited with exit status 15.

pid is 24503.

fork() is ok and child pid is  24565

child has exited with status 0.
