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_DeleteCloseHandler does nothing if its proc and clientData arguments do not match the proc and clientData for a close handler for channel.
