The following implementation of realloc (language C) is can be seen in the image below:

Given this implementation, answer the following questions with respect to the provided information:

void new_realloc(void *oldptr, size t newsz) if (newsz0) free(oldptr); return NULL; // the following is a call to a placeholder function // for internal information managed by the heap allocator size-t move sz bytes-to move(oldptr, news z); if (movesz) /the allocator determined it had space, so // it updated its own records and we just return // the old pointer return oldptr; // if the allocator couldn't leave in place, must malloc and move void *newptr malloc(newsz); if (newptr != NULL && oldptr != NULL) { memcpy(newptr, oldptr, movesz); free(oldptr); return newptr
