stream-output-timeout

Arguments: simple-stream

This generic function returns the output timeout limit for simple-stream, which may be nil (no limit) or a positive integer noting how many seconds to wait for output before erroring because there is no output on the stream.

Timeouts may be particularly useful for socket streams. The example (using the related stream-input-timeout) is for demonstration only and is not recommended:

;; For demonstration only. Do not try this at home!
cl-user(3): (setf (stream-input-timeout *standard-output*) 3)

3
cl-user(4):  ;; we do not type anything and we get an error:
Error: #<stream-error @ #x10000e35692>
  [condition type: stream-error]

Restart actions (select using :continue):
 0: Return to Top Level (an "abort" restart).
 1: Abort entirely from this (lisp) process.
[1] cl-user(5): ;; repeated errors:
Error: #<stream-error @ #x10000e35692>
  [condition type: stream-error]

Restart actions (select using :continue):
 0: Return to Debug Level 1 (an "abort" restart).
 1: Return to Top Level (an "abort" restart).
 2: Abort entirely from this (lisp) process.
[2] cl-user(6): (setf (stream-input-timeout *standard-output*) nil)
    ;; we set the value back.

nil
[2] cl-user(7): :res
cl-user(8):  ;; no more errors.
