Tcl_RecordAndEval(3) Tcl Library Procedures 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 do not 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 do not want the command recorded on the history list then you should invoke Tcl_Eval instead of Tcl_RecordAn-
dEval. 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.
