ClientData clientData (in) Arbitrary one-word value to pass to proc.
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(
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-
