Tcl_RecordAndEvalObj(3) 				      Tcl Library Procedures					   Tcl_RecordAndEvalObj(3)

__________________________________________________________________________________________________________________________________________________

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 do not 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_Global-
       EvalObj	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 object 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.
