.SH DESCRIPTION
|
||
|
|
.PP
|
||
|
|
\fBTcl_RecordAndEval\fR is invoked to record a command as an event
|
||
|
|
on the history list and then execute it using \fBTcl_Eval\fR
|
||
|
|
(or \fBTcl_GlobalEval\fR if the TCL_EVAL_GLOBAL bit is set in \fIflags\fR).
|
||
|
|
It returns a completion code such as TCL_OK just like \fBTcl_Eval\fR
|
||
|
|
and it leaves information in \fIinterp->result\fR.
|
||
|
|
If you don't want the command recorded on the history list then
|
||
|
|
you should invoke \fBTcl_Eval\fR instead of \fBTcl_RecordAndEval\fR.
|
||
|
|
Normally \fBTcl_RecordAndEval\fR 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 \fIflags\fR argument contains the TCL_NO_EVAL bit then
|
||
|
|
the command is recorded without being evaluated.
