The program shown below uses the Pthreads API. What would be the output from the program at LINE C and LINE P? Motivate your answer.

#include

#include

int value = 0;

void *runner(void *param); /* the thread */

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

{

pid t pid;

pthread t tid;

pthread attr t attr;

pid = fork();

if (pid == 0) { /* child process */

pthread attr init(&attr);

pthread create(&tid,&attr,runner,NULL);

pthread join(tid,NULL);

printf("CHILD: value = %d",value); /* LINE C */

}

else if (pid > 0) { /* parent process */

wait(NULL);

printf("PARENT: value = %d",value); /* LINE P */

}

}

void *runner(void *param) {

value = 5;

pthread exit(0);

}
