Print out value of stack pointer

by

One trick, which is not portable or really even guaranteed to work, is to simple print out the address of a local as a pointer. 

void print_stack_pointer() {
  void* p = NULL;
  printf("%p", (void*)&p);
}

This will essentially print out the address of p which is a good approximation of the current stack pointer
