int Tcl_RecordAndEvalObj(interp, cmdPtr, flags)


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.


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.
