Tcl_RecordAndEvalObj(3) Tcl Library Procedures Tcl_RecordAndEvalObj(3)
Tcl_RecordAndEvalObj - save command on history list before evaluating
Tcl_RecordAndEvalObj(interp, cmdPtr, flags)
Tcl_Interp *interp (in) Tcl interpreter in which to evaluate
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.
