tcl_deleteclosehandler
Tcl_CreateCloseHandler(3) Tcl Library Procedures Tcl_CreateCloseHandler(3)__________________________________________________________________________________________________________________________________________________NAME
Tcl_CreateCloseHandler, Tcl_DeleteCloseHandler - arrange for callbacks when channels are closed
SYNOPSIS
#include <tcl.h>
void
Tcl_CreateCloseHandler(channel, proc, clientData)
void
Tcl_DeleteCloseHandler(channel, proc, clientData)
ARGUMENTS
Tcl_Channel channel (in) The channel for which to create or delete a close callback.
Tcl_CloseProc *proc (in) The procedure to call as the callback.
ClientData clientData (in) Arbitrary one-word value to pass to proc.
_________________________________________________________________DESCRIPTION
Tcl_CreateCloseHandler arranges for proc to be called when channel is closed with Tcl_Close or Tcl_UnregisterChannel, or using the Tcl
close command. Proc should match the following prototype:
typedef void Tcl_CloseProc(
ClientData clientData);
The clientData is the same as the value provided in the call to Tcl_CreateCloseHandler.
Tcl_DeleteCloseHandler removes a close callback for channel. The proc and clientData identify which close callback to remove; Tcl_Delete-
CloseHandler does nothing if its proc and clientData arguments do not match the proc and clientData for a close handler for channel.
