|
||
|
|
|
||
|
|
<p>The TUI has specific commands to control the text windows.
|
||
|
|
These commands are always available, even when <small>GDB</small> is not in
|
||
|
|
the TUI mode. When <small>GDB</small> is in the standard mode, most
|
||
|
|
of these commands will automatically switch to the TUI mode.
|
||
|
|
</p>
|
||
|
|
<p>Note that if <small>GDB</small>’s <code>stdout</code> is not connected to a
|
||
|
|
terminal, or <small>GDB</small> has been started with the machine interface
|
||
|
|
interpreter (see <a href="GDB_002fMI.html#GDB_002fMI">The <small>GDB/MI</small> Interface</a>), most of
|
||
|
|
these commands will fail with an error, because it would not be
|
||
|
|
possible or desirable to enable curses window management.
|
||
|
|
</p>
