Tcl_RecordAndEvalObj -
save command on history list before evaluating
#include <tcl.h> int Tcl_RecordAndEvalObj(interp, cmdPtr, flags)
| Type | Name | Mode |
|---|---|---|
| Tcl_Interp | *interp | in |
| Tcl interpreter in which to evaluate command. | ||
| Tcl_Obj | *cmdPtr | in |
| Points to a Tcl value 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. | ||
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 value 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.
