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_CallWhenDeleted. 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, and clientData then the call to Tcl_DontCallWhenDeleted has no effect.
