  17         unsigned int seconds )

  19 /*  FUNCTION
  20         The sleep() function makes the current process sleep for the
  21         specified number of seconds or until a signal arrives which
  22         is not ignored.
  23
  24     INPUTS
  25         seconds - The number of seconds to sleep
  26
  27     RESULT
  28         Zero if the requested time has elapsed, or the number of seconds
  29         left to sleep when the process was signalled.

  33     EXAMPLE
  34         // Sleep for 10 seconds
  35         sleep( 10 );
  36
  37     BUGS
  38         The current implementation simply uses the dos.library function
  39         Delay() to sleep, and cannot be interrupted by incoming signals.
  40         This shouldn't be of any importance, since AROS doesn't have
  41         POSIX style signalling yet (but when it is implemented, this
  42         function needs to be changed).
