  13. How do I allocate a port from within a kernel server? The documention
  14. for hmap lists the following:
  15.  
  16. /* Create the port. */
  17. r = port_allocate((task_t)task_self(), &port_name);
  18.  
  19. which can't possibly work, since task_self is not defined in the kernel.
  20.  
  21. I tried various combinations of current_task() and convert_task_to_port(),
  22. none of which worked.
  23.  
  24. Could someone who has done this tell me how?
