Access to symbol table data maintained by <span class="sc">gdb</span> on the inferior
is exposed to Python via two objects: <code>gdb.Symtab_and_line</code> and
<code>gdb.Symtab</code>. Symbol table and line data for a frame is returned
from the <code>find_sal</code> method in <code>gdb.Frame</code> object.
See <a href="Frames-In-Python.html#Frames-In-Python">Frames In Python</a>.
<p>For more information on <span class="sc">gdb</span>'s symbol table management, see
<a href="Symbols.html#Symbols">Examining the Symbol Table</a>, for more information.
<p>A <code>gdb.Symtab_and_line</code> object has the following attributes:
<dl>
<div class="defun">
&mdash; Instance Variable of Symtab_and_line: <b>symtab</b><var><a name="index-symtab-1899"></a></var><br>
<blockquote> <p>The symbol table object (<code>gdb.Symtab</code>) for this frame.
This attribute is not writable.
</p></blockquote></div>
<div class="defun">
&mdash; Instance Variable of Symtab_and_line: <b>pc</b><var><a name="index-pc-1900"></a></var><br>
<blockquote> <p>Indicates the current program counter address. This attribute is not
writable.
</p></blockquote></div>
<div class="defun">
&mdash; Instance Variable of Symtab_and_line: <b>line</b><var><a name="index-line-1901"></a></var><br>
<blockquote> <p>Indicates the current line number for this object. This
attribute is not writable.
</p></blockquote></div>
</dl>
<p>A <code>gdb.Symtab</code> object has the following attributes:
<dl>
<div class="defun">
&mdash; Instance Variable of Symtab: <b>filename</b><var><a name="index-filename-1902"></a></var><br>
<blockquote> <p>The symbol table's source filename. This attribute is not writable.
</p></blockquote></div>
<div class="defun">
&mdash; Instance Variable of Symtab: <b>objfile</b><var><a name="index-objfile-1903"></a></var><br>
<blockquote> <p>The symbol table's backing object file. See <a href="Objfiles-In-Python.html#Objfiles-In-Python">Objfiles In Python</a>.

<p>The following methods are provided:
<dl>
<div class="defun">
&mdash; Method on Symtab: <b>fullname</b><var><a name="index-fullname-on-Symtab-1904"></a></var><br>
