Tcl - Tcl_RecordAndEval (3)

Tcl Library Procedures

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.
