Tcl_RecordAndEvalObj - save command on history list before
evaluating
#include <tcl.h>
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.
