Tcl_CallWhenDeleted: Arrange for callback when interpreter is deleted
Tcl_CallWhenDeleted, Tcl_DontCallWhenDeleted - Arrange for callback when interpreter is deleted
#include <tcl.h> Tcl_CallWhenDeleted(interp, proc, clientData) Tcl_DontCallWhenDeleted(interp, proc, clientData)
- Tcl_Interp *interp (in) Interpreter with which to associated callback.
- Tcl_InterpDeleteProc *proc (in) Procedure to call when interp is deleted.
ClientData clientData (in)
Arbitrary one-word value to pass to proc.
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);
Tcl_DontCallWhenDeleted cancels a previous call to Tcl_CallWhenDeleted with the same arguments, so that proc will not 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.
