Tcl_RecordAndEval(3Tcl)Tcl_RecordAndEval(3Tcl)NAME
Tcl_RecordAndEval - save command on history list before evaluating
SYNOPSIS
#include <tcl.h>
int
Tcl_RecordAndEval(interp, cmd, eval)
ARGUMENTS
Tcl_Interp *interp (in) Tcl interpreter in which to evaluate
command.
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 interp->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.
