| 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>. |
