<p><a name="index-objfiles-in-guile-2664"></a><a name="index-g_t_003cgdb_003aobjfile_003e-2665"></a><span class="sc">gdb</span> loads symbols for an inferior from various
symbol-containing files (see <a href="Files.html#Files">Files</a>). These include the primary
executable file, any shared libraries used by the inferior, and any
separate debug info files (see <a href="Separate-Debug-Files.html#Separate-Debug-Files">Separate Debug Files</a>).
<span class="sc">gdb</span> calls these symbol-containing files <dfn>objfiles</dfn>.
<p>Each objfile is represented as an object of type <code>&lt;gdb:objfile&gt;</code>.
<p>The following objfile-related procedures are provided by the
<code>(gdb)</code> module:
<div class="defun">
&mdash; Scheme Procedure: <b>objfile?</b><var> object<a name="index-objfile_003f-2666"></a></var><br>
<blockquote><p>Return <code>#t</code> if <var>object</var> is a <code>&lt;gdb:objfile&gt;</code> object.
Otherwise return <code>#f</code>.
</p></blockquote></div>
<div class="defun">
&mdash; Scheme Procedure: <b>objfile-valid?</b><var> objfile<a name="index-objfile_002dvalid_003f-2667"></a></var><br>
<blockquote><p>Return <code>#t</code> if <var>objfile</var> is valid, <code>#f</code> if not.
A <code>&lt;gdb:objfile&gt;</code> object can become invalid
if the object file it refers to is not loaded in <span class="sc">gdb</span> any
longer. All other <code>&lt;gdb:objfile&gt;</code> procedures will throw an exception
if it is invalid at the time the procedure is called.
</p></blockquote></div>
<div class="defun">
&mdash; Scheme Procedure: <b>objfile-filename</b><var> objfile<a name="index-objfile_002dfilename-2668"></a></var><br>
<blockquote><p>Return the file name of <var>objfile</var> as a string,
with symbolic links resolved.
</p></blockquote></div>
<div class="defun">
&mdash; Scheme Procedure: <b>objfile-progspace</b><var> objfile<a name="index-objfile_002dprogspace-2669"></a></var><br>
<blockquote><p>Return the <code>&lt;gdb:progspace&gt;</code> that this object file lives in.
See <a href="Progspaces-In-Guile.html#Progspaces-In-Guile">Progspaces In Guile</a>, for more on progspaces.
</p></blockquote></div>
<div class="defun">
&mdash; Scheme Procedure: <b>objfile-pretty-printers</b><var> objfile<a name="index-objfile_002dpretty_002dprinters-2670"></a></var><br>
<blockquote><p>Return the list of registered <code>&lt;gdb:pretty-printer&gt;</code> objects for
