ARGUMENTS <\/a> <\/h2>\n\n\n\n\n
<\/td>\n\n

Tcl_Interp *interp<\/i> (in)<\/p>\n<\/td>\n

<\/td>\n\n

Tcl interpreter in which to evaluate command.<\/p>\n<\/td>\n<\/tr>\n

<\/td>\n\n

Tcl_Obj *cmdPtr<\/i> (in)<\/p>\n<\/td>\n

<\/td>\n\n

Points to a Tcl value containing a command (or sequence of commands) to execute.<\/p>\n<\/td>\n<\/tr>\n

<\/td>\n\n

int flags<\/i> (in)<\/p>\n<\/td>\n

<\/td>\n\n

An OR\u2019ed combination of flag bits. TCL_NO_EVAL<\/b> means record the command but do not evaluate it. TCL_EVAL_GLOBAL<\/b> means evaluate the command at global level instead of the current stack level.<\/p>\n<\/td>\n<\/tr>\n<\/table>\n

DESCRIPTION <\/a> <\/h2>\n

Tcl_RecordAndEvalObj<\/b> is invoked to record a command as an event on the history list and then execute it using Tcl_EvalObjEx<\/b> (or Tcl_GlobalEvalObj<\/b> if the TCL_EVAL_GLOBAL<\/b> bit is set in flags<\/i>). It returns a completion code such as TCL_OK<\/b> just like Tcl_EvalObjEx<\/b>, as well as a result value containing additional information (a result value or error message) that can be retrieved using Tcl_GetObjResult<\/b>. If you do not want the command recorded on the history list then you should invoke Tcl_EvalObjEx<\/b> instead of Tcl_RecordAndEvalObj<\/b>. Normally Tcl_RecordAndEvalObj<\/b> 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<\/i> argument contains the TCL_NO_EVAL<\/b> bit then the command is recorded without being evaluated.<\/p>\n
