Tcl_RecordAndEvalObj - save command on history list before evaluating
Tcl_RecordAndEvalObj(interp, cmdPtr, flags)
- Tcl_Interp *interp (in)
- Tcl interpreter in which to evaluate command.
- Tcl_Obj *cmdPtr (in)
- Points to a Tcl value containing a command (or sequence of commands) to
- int flags (in)
- An OR'ed combination of flag bits. TCL_NO_EVAL means record the
command but do not evaluate it. TCL_EVAL_GLOBAL means evaluate the
command at global level instead of the current stack level.
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 in
flags). 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.
