'\" The definitions below are for supplemental macros used in Tcl/Tk
'\" manual entries.
'\"
'\" .AP type name in/out ?indent?
'\"	Start paragraph describing an argument to a library procedure.
'\"	type is type of argument (int, etc.), in/out is either "in", "out",
'\"	or "in/out" to describe whether procedure reads or modifies arg,
'\"	and indent is equivalent to second arg of .IP (shouldn't ever be
'\"	needed;  use .AS below instead)
'\"
'\" .AS ?type? ?name?
'\"	Give maximum sizes of arguments for setting tab stops.  Type and
'\"	name are examples of largest possible arguments that will be passed
'\"	to .AP later.  If args are omitted, default tab stops are used.
'\"
'\" .BS
'\"	Start box enclosure.  From here until next .BE, everything will be
'\"	enclosed in one large box.
'\"
'\" .BE
'\"	End of box enclosure.
'\"
'\" .CS
'\"	Begin code excerpt.
'\"
'\" .CE
'\"	End code excerpt.
'\"
'\" .VS ?version? ?br?
'\"	Begin vertical sidebar, for use in marking newly-changed parts
'\"	of man pages.  The first argument is ignored and used for recording
'\"	the version when the .VS was added, so that the sidebars can be
'\"	found and removed when they reach a certain age.  If another argument
'\"	is present, then a line break is forced before starting the sidebar.
'\"
'\" .VE
'\"	End of vertical sidebar.
'\"
'\" .DS
'\"	Begin an indented unfilled display.
'\"
'\" .DE
'\"	End of indented unfilled display.
'\"
'\" .SO
'\"	Start of list of standard options for a Tk widget.  The
'\"	options follow on successive lines, in four columns separated
'\"	by tabs.
'\"
'\" .SE
'\"	End of list of standard options for a Tk widget.
'\"
'\" .OP cmdName dbName dbClass
'\"	Start of description of a specific option.  cmdName gives the
'\"	option's name as specified in the class command, dbName gives
'\"	the option's name in the option database, and dbClass gives
'\"	the option's class in the option database.
'\"
'\" .UL arg1 arg2
'\"	Print arg1 underlined, then print arg2 normally.

.SH NAME
Tcl_RecordAndEvalObj \- save command on history list before evaluating
.SH SYNOPSIS
.nf
\fB#include <tcl.h>\fR
.sp
int
\fBTcl_RecordAndEvalObj\fR(\fIinterp, cmdPtr, flags\fR)
.SH ARGUMENTS
.AS Tcl_Interp *interp;
.AP Tcl_Interp *interp in
Tcl interpreter in which to evaluate command.
.AP Tcl_Obj *cmdPtr in
Points to a Tcl object containing a command (or sequence of commands)
to execute.
.AP 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.
.BE

.SH DESCRIPTION
.PP
\fBTcl_RecordAndEvalObj\fR is invoked to record a command as an event
on the history list and then execute it using \fBTcl_EvalObjEx\fR
(or \fBTcl_GlobalEvalObj\fR if the TCL_EVAL_GLOBAL bit is set
in \fIflags\fR).
It returns a completion code such as TCL_OK just like \fBTcl_EvalObjEx\fR,
as well as a result object containing additional information
(a result value or error message)
that can be retrieved using \fBTcl_GetObjResult\fR.
If you don't want the command recorded on the history list then
you should invoke \fBTcl_EvalObjEx\fR instead of \fBTcl_RecordAndEvalObj\fR.
Normally \fBTcl_RecordAndEvalObj\fR 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 \fIflags\fR argument contains the TCL_NO_EVAL bit then
the command is recorded without being evaluated.
