-Tcl_CallWhenDeleted, Tcl_DontCallWhenDeleted \- Arrange for callback when interpreter is deleted
-.SH SYNOPSIS

-.SH ARGUMENTS
-.AS Tcl_InterpDeleteProc clientData
-.AP Tcl_Interp *interp in
-Interpreter with which to associated callback.
-.AP Tcl_InterpDeleteProc *proc in

-.SH DESCRIPTION
-.PP
-\fBTcl_CallWhenDeleted\fR arranges for \fIproc\fR to be called by
-\fBTcl_DeleteInterp\fR if/when \fIinterp\fR is deleted at some future
-time. \fIProc\fR will be invoked just before the interpreter
-is deleted, but the interpreter will still be valid at the
-time of the call.
-\fIProc\fR should have arguments and result that match the
-type \fBTcl_InterpDeleteProc\fR:
-.CS
-typedef void Tcl_InterpDeleteProc(
- ClientData \fIclientData\fR,
- Tcl_Interp *\fIinterp\fR);
-.CE
-The \fIclientData\fR and \fIinterp\fR parameters are
-copies of the \fIclientData\fR and \fIinterp\fR arguments given
-to \fBTcl_CallWhenDeleted\fR.
-Typically, \fIclientData\fR points to an application-specific
-data structure that \fIproc\fR uses to perform cleanup when an
-interpreter is about to go away.
-\fIProc\fR does not return a value.
-.PP
-\fBTcl_DontCallWhenDeleted\fR cancels a previous call to
-\fBTcl_CallWhenDeleted\fR with the same arguments, so that
-\fIproc\fR will not be called after all when \fIinterp\fR is
-deleted.
-If there is no deletion callback that matches \fIinterp\fR,
-\fIproc\fR, and \fIclientData\fR then the call to
-\fBTcl_DontCallWhenDeleted\fR has no effect.
