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.
