NAME
Tcl_CreateCloseHandler, Tcl_DeleteCloseHandler - arrange for callbacks when channels are closedSYNOPSIS
#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.
