Tcl_CreateCloseHandler, Tcl_DeleteCloseHandler \u2212 arrange for callbacks when channels are closed<\/p>\n

SYNOPSIS <\/a> <\/h2>\n

#include <\/b><\/p>\n

void
Tcl_CreateCloseHandler<\/b>(channel, proc, clientData<\/i>)<\/p>\n

void
Tcl_DeleteCloseHandler<\/b>(channel, proc, clientData<\/i>)<\/p>\n

ARGUMENTS <\/a> <\/h2>\n\n\n\n\n
<\/td>\n\n

Tcl_Channel channel<\/i> (in)<\/p>\n<\/td>\n

<\/td>\n\n

The channel for which to create or delete a close callback.<\/p>\n<\/td>\n<\/tr>\n

<\/td>\n\n

Tcl_CloseProc *proc<\/i> (in)<\/p>\n<\/td>\n

<\/td>\n\n

The procedure to call as the callback.<\/p>\n<\/td>\n<\/tr>\n

<\/td>\n\n

ClientData clientData<\/i> (in)<\/p>\n<\/td>\n

<\/td>\n\n

Arbitrary one-word value to pass to proc<\/i>.<\/p>\n<\/td>\n<\/tr>\n<\/table>\n

DESCRIPTION <\/a> <\/h2>\n

Tcl_CreateCloseHandler<\/b> arranges for proc<\/i> to be called when channel<\/i> is closed with Tcl_Close<\/b> or Tcl_UnregisterChannel<\/b>, or using the Tcl close<\/b> command. Proc<\/i> should match the following prototype:<\/p>\n

typedef void Tcl_CloseProc<\/b>(
ClientData clientData<\/i>);<\/p>\n

The clientData<\/i> is the same as the value provided in the call to Tcl_CreateCloseHandler<\/b>.<\/p>\n

Tcl_DeleteCloseHandler<\/b> removes a close callback for channel<\/i>. The proc<\/i> and clientData<\/i> identify which close callback to remove; Tcl_DeleteCloseHandler<\/b> does nothing if its proc<\/i> and clientData<\/i> arguments do not match the proc<\/i> and clientData<\/i> for a close handler for channel<\/i>.<\/p>\n
