The fоllоwing Pthreаd C prоgrаm is intended to synchronize pаrent and child thread execution to produce the following output. parent: beginchildparent: end However, when this program executes, the parent thread occasionally freezes prior to print "parent: end". First, explain why this happens. Second, copy the program source to the answer box and fix the problem(s). If you need, you can refer to Pthread reference link. #include #include #include pthread_mutex_t m = PTHREAD_MUTEX_INITIALIZER;pthread_cond_t c = PTHREAD_COND_INITIALIZER;void thr_exit() { pthread_mutex_lock(&m); pthread_cond_signal(&c); pthread_mutex_unlock(&m);}void *child(void *arg) { printf("childn"); thr_exit();}void thr_join() { pthread_mutex_lock(&m) pthread_cond_wait(&c, &m); pthread_mutex_unlock(&m);}int main(int argc, char *argv[]) { printf("parent: beginn"); pthread_t p; pthread_create(&p, NULL, child, NULL); thr_join(); printf("parent: endn"); return 0;}
