command.
Tcl_Obj *cmdPtr (in) Points to a Tcl value containing a
command (or sequence of commands) to

DESCRIPTION
Tcl_RecordAndEvalObj is invoked to record a command as an event on the
history list and then execute it using Tcl_EvalObjEx (or Tcl_GlobalE-
valObj if the TCL_EVAL_GLOBAL bit is set in flags). It returns a com-
pletion code such as TCL_OK just like Tcl_EvalObjEx, as well as a re-
sult 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_RecordAn-
dEvalObj 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.
