NAME
       Tcl_RecordAndEvalObj - save command on history list before evaluating

SYNOPSIS
       #include <tcl.h>

       int
       Tcl_RecordAndEvalObj(interp, cmdPtr, flags)

ARGUMENTS
       Tcl_Interp   *interp    (in)      Tcl  interpreter in which to evaluate
                                         command.

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

       int          flags      (in)      An OR'ed combination  of  flag  bits.
                                         TCL_NO_EVAL  means record the command
                                         but      don't      evaluate      it.
                                         TCL_EVAL_GLOBAL  means  evaluate  the
                                         command at global  level  instead  of
                                         the current stack level.

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
       result  object  containing  additional  information  (a result value or
       error message) that can be retrieved using  Tcl_GetObjResult.   If  you
       don't  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.
