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_GlobalEvalObj 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 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.
