_________________________________________________________________
Tcl_CallWhenDeleted arranges for proc to be called by
Tcl_DeleteInterp if/when interp is deleted at some future
time. Proc will be invoked just before the interpreter is
deleted, but the interpreter will still be valid at the
time of the call. Proc should have arguments and result
that match the type Tcl_InterpDeleteProc:
typedef void Tcl_InterpDeleteProc(
ClientData clientData,
Tcl_Interp *interp);
The clientData and interp parameters are copies of the
clientData and interp arguments given to Tcl_CallWhen
Deleted. Typically, clientData points to an application-
specific data structure that proc uses to perform cleanup
when an interpreter is about to go away. Proc does not
return a value.
Tcl_DontCallWhenDeleted cancels a previous call to
Tcl_CallWhenDeleted with the same arguments, so that proc
won't be called after all when interp is deleted. If
there is no deletion callback that matches interp, proc,
Tcl_CallWhenDeleted(3)Tcl Library ProcedureTcl_CallWhenDeleted(3)
and clientData then the call to Tcl_DontCallWhenDeleted
has no effect.
