|
<a name="index-GDB_002fMI_002c-its-purpose"></a>
|
|
<p><small>GDB/MI</small> is a line based machine oriented text interface to
|
|
<small>GDB</small> and is activated by specifying using the
|
|
<samp>--interpreter</samp> command line option (see <a href="Mode-Options.html#Mode-Options">Mode Options</a>). It
|
|
is specifically intended to support the development of systems which
|
|
use the debugger as just one small component of a larger system.
|
|
</p>
|
|
<p>This chapter is a specification of the <small>GDB/MI</small> interface. It is written
|
|
in the form of a reference manual.
|
|
</p>
|
|
<p>Note that <small>GDB/MI</small> is still under construction, so some of the
|
|
features described below are incomplete and subject to change
|
|
(see <a href="GDB_002fMI-Development-and-Front-Ends.html#GDB_002fMI-Development-and-Front-Ends"><small>GDB/MI</small> Development and Front Ends</a>).

<p>This chapter uses the following notation:
|
|
</p>
|
|
<ul>
|
|
<li> <code>|</code> separates two alternatives.
|
|
|
|
</li><li> <code>[ <var>something</var> ]</code> indicates that <var>something</var> is optional:
|
|
it may or may not be given.
|
|
|
|
</li><li> <code>( <var>group</var> )*</code> means that <var>group</var> inside the parentheses
|
|
may repeat zero or more times.
|
|
|
|
</li><li> <code>( <var>group</var> )+</code> means that <var>group</var> inside the parentheses
|
|
may repeat one or more times.
|
|
|
|
</li><li> <code>"<var>string</var>"</code> means a literal <var>string</var>.
|
|
</li></ul>
