Tcl_RecordAndEvalObj — save command on history list before evaluating
Tcl_RecordAndEvalObj(interp, cmdPtr, flags)
Tcl_RecordAndEvalObj is invoked to record a command as an event
on the history list and then execute it using Tcl_EvalObjEx
(or Tcl_GlobalEvalObj if the TCL_EVAL_GLOBAL bit is set
It returns a completion code such as TCL_OK just like Tcl_EvalObjEx,
as well as a result value containing additional information
(a result value or error message)
that can be retrieved using Tcl_GetObjResult.
If you do not want the command recorded on the history list then
you should invoke Tcl_EvalObjEx instead of Tcl_RecordAndEvalObj.
Normally Tcl_RecordAndEvalObj is only called with top-level
commands typed by the user, since the purpose of history is to
allow the user to re-issue recently invoked commands.
If the flags argument contains the TCL_NO_EVAL bit then
the command is recorded without being evaluated.
