Subject: start-process and set-process-filter sequence
Date: Thu, 14 Apr 2011 11:10:20 +0800 [thread overview]
Message-ID: <21glbp094jfn.fsf@gmail.com> (raw)
Hi,
Because set-process-filter will be done after the process is created by
start-process, it seems there is a possibility that the filter may miss
some process output. Consider this:
(defun foo (proc output)
(setq a output))
(let ((proc (start-process "ls" "ls" "ls")))
;; (read-string "Mood: ")
(setq a nil)
(set-process-filter proc 'foo))
Compare comment and uncomment the read-string line, `a' would be
different.
Is there a way to set a process filter before the process starts? so
that we won't miss any output.
