  13. I am trying to emulate the nodelay function in the System V
  14. implementation of curses, but I am having no luck.  I assume that I
  15. need to set a flag to make non-blocking reads with stdin.  I have
  16. tried using fcntl() with no avail.  This is what I think should work -
  17.  
  18.     fok = fcntl(stdin, F_SETFL, FNDELAY);
  19.  
  20. I know that this is wrong, but I cannot come up with the correct call.
  21.  
  22. Could someone please explain what I am doing wrong and show me the
  23. correct code?
  24.

  26. Thank you
