.SH DESCRIPTION
|
| 34 |
|
|
.PP
|
| 35 |
|
|
\fBTcl_RecordAndEvalObj\fR is invoked to record a command as an event
|
| 36 |
|
|
on the history list and then execute it using \fBTcl_EvalObj\fR
|
| 37 |
|
|
(or \fBTcl_GlobalEvalObj\fR if the TCL_EVAL_GLOBAL bit is set
|
| 38 |
|
|
in \fIflags\fR).
|
| 39 |
|
|
It returns a completion code such as TCL_OK just like \fBTcl_EvalObj\fR,
|
| 40 |
|
|
as well as a result object containing additional information
|
| 41 |
|
|
(a result value or error message)
|
| 42 |
|
|
that can be retrieved using \fBTcl_GetObjResult\fR.
|
| 43 |
|
|
If you don't want the command recorded on the history list then
|
| 44 |
|
|
you should invoke \fBTcl_EvalObj\fR instead of \fBTcl_RecordAndEvalObj\fR.
|
| 45 |
|
|
Normally \fBTcl_RecordAndEvalObj\fR is only called with top-level
|
| 46 |
|
|
commands typed by the user, since the purpose of history is to
|
| 47 |
|
|
allow the user to re-issue recently-invoked commands.
|
| 48 |
|
|
If the \fIflags\fR argument contains the TCL_NO_EVAL bit then
|
| 49 |
|
|
the command is recorded without being evaluated.
