From 274a9425361237d6623f2f27d6267eef45a2adfc Mon Sep 17 00:00:00 2001 From: "Richard M. Stallman" Date: Sat, 25 Jun 1994 22:34:52 +0000 Subject: [PATCH] (send_process): Major rewrite. Don't put in a C-d unless a single line is too long. Read process input whenever output gets stuck. Relocate BUF if we read input. New arg OBJECT. (Fprocess_send_region, Fprocess_send_string, process_send_signal) (Fprocess_send_eof): Pass new arg OBJECT. --- src/buffer.c | 28 ++++++++++++++++++---------- 1 file changed, 18 insertions(+), 10 deletions(-) diff --git a/src/buffer.c b/src/buffer.c index 3eb61de0c82..9561035e334 100644 --- a/src/buffer.c +++ b/src/buffer.c @@ -2115,25 +2115,33 @@ DEFUN ("overlay-put", Foverlay_put, Soverlay_put, 3, 3, 0, (overlay, prop, value) Lisp_Object overlay, prop, value; { - Lisp_Object plist, tail; + Lisp_Object plist, tail, buffer; CHECK_OVERLAY (overlay, 0); - tail = Fmarker_buffer (OVERLAY_START (overlay)); - if (!
