From 59a00f60a2573aeca8a788c18f34e5a8f9c5702a Mon Sep 17 00:00:00 2001 From: vasiljevic Date: Tue, 4 Oct 2005 18:15:09 +0000 Subject: Tcl_ClearChannelHandlers(): now deletes any outstanding timer for the channel. Also, prevents events still in the event queue from triggering on the current channel. --- generic/tclIO.c | 16 ++++++++++++++-- 1 file changed, 14 insertions(+), 2 deletions(-) diff --git a/generic/tclIO.c b/generic/tclIO.c index f983a9a..ccc107b 100644 --- a/generic/tclIO.c +++ b/generic/tclIO.c @@ -10,7 +10,7 @@ * See the file "license.terms" for information on usage and redistribution * of this file, and for a DISCLAIMER OF ALL WARRANTIES. * - * RCS: @(#) $Id: tclIO.c,v 1.61.2.11 2005/06/22 19:35:16 kennykb Exp $ + * RCS: @(#) $Id: tclIO.c,v 1.61.2.12 2005/10/04 18:15:09 vasiljevic Exp $ */ #include "tclInt.h" @@ -2659,6 +2659,12 @@ Tcl_ClearChannelHandlers (channel) chanPtr = statePtr->topChanPtr; /* + * Cancel any outstanding timer. + */ + + Tcl_DeleteTimerHandler(statePtr->timer); + + /* * Remove any references to channel handlers for this channel that * may be about to be invoked. */ @@ -2696,10 +2702,16 @@ Tcl_ClearChannelHandlers (channel) * will occur if Tcl_DoOneEvent is called before the channel is * finally deleted in FlushChannel.
