Tcl_RecordAndEval — save command on history list before evaluating
#include <tcl.h>
int
Tcl_RecordAndEval(interp, cmd, flags)
- Tcl_Interp *interp (in)
-
Tcl interpreter in which to evaluate command.
- const char *cmd (in)
-
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_RecordAndEval is invoked to record a command as an event
on the history list and then execute it using Tcl_Eval
(or Tcl_GlobalEval if the TCL_EVAL_GLOBAL bit is set in flags).
It returns a completion code such as TCL_OK just like Tcl_Eval
and it leaves information in the interpreter's result.
If you do not want the command recorded on the history list then
you should invoke Tcl_Eval instead of Tcl_RecordAndEval.
Normally Tcl_RecordAndEval 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.
Note that Tcl_RecordAndEval has been largely replaced by the
value-based procedure Tcl_RecordAndEvalObj.
That value-based procedure records and optionally executes
a command held in a Tcl value instead of a string.
