tcl_recordandeval(3)
NAME
Tcl_RecordAndEval - save command on history list before
evaluating
SYNOPSIS
#include <tcl.h> int Tcl_RecordAndEval(interp, cmd, flags)
ARGUMENTS
- 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 don't evaluate it.
TCL_EVAL_GLOBAL means
evaluate the command at
global level instead of
the current stack level.
DESCRIPTION
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 don't 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 object-based procedure Tcl_RecordAndEvalObj. That
object-based procedure records and optionally executes a
command held in a Tcl object instead of a string.
