| |
| <p><a name="index-blocks-in-python-1833"></a><a name="index-gdb_002eBlock-1834"></a> |
| Within each frame, <span class="sc">gdb</span> maintains information on each block |
| stored in that frame. These blocks are organized hierarchically, and |
| are represented individually in Python as a <code>gdb.Block</code>. |
| Please see <a href="Frames-In-Python.html#Frames-In-Python">Frames In Python</a>, for a more in-depth discussion on |
| frames. Furthermore, see <a href="Stack.html#Stack">Examining the Stack</a>, for more |
| detailed technical information on <span class="sc">gdb</span>'s book-keeping of the |
| stack. |
| |
| <p>The following block-related functions are available in the <code>gdb</code> |
| module: |
| |
| <p><a name="index-gdb_002eblock_005ffor_005fpc-1835"></a> |
| |
| <div class="defun"> |
| — Function: <b>block_for_pc</b><var> pc<a name="index-block_005ffor_005fpc-1836"></a></var><br> |
| <blockquote><p>Return the <code>gdb.Block</code> containing the given <var>pc</var> value. If the |
| block cannot be found for the <var>pc</var> value specified, the function |
| will return <code>None</code>. |
| </p></blockquote></div> |
| |
| <p>A <code>gdb.Block</code> object has the following attributes: |
| |
| <dl> |
| |
| <div class="defun"> |
| — Instance Variable of Block: <b>start</b><var><a name="index-start-1837"></a></var><br> |
| <blockquote> <p>The start address of the block. This attribute is not writable. |
| </p></blockquote></div> |
| |
| <div class="defun"> |
| — Instance Variable of Block: <b>end</b><var><a name="index-end-1838"></a></var><br> |
| <blockquote> <p>The end address of the block. This attribute is not writable. |
| </p></blockquote></div> |
| |
| <div class="defun"> |
| — Instance Variable of Block: <b>function</b><var><a name="index-function-1839"></a></var><br> |
| <blockquote> <p>The name of the block represented as a <code>gdb.Symbol</code>. If the |
| block is not named, then this attribute holds <code>None</code>. This |
| attribute is not writable. |
| </p></blockquote></div> |
| |
| <div class="defun"> |
| — Instance Variable of Block: <b>superblock</b><var><a name="index-superblock-1840"></a></var><br> |
| <blockquote> <p>The block containing this block. If this parent block does not exist, |
| this attribute holds <code>None</code>. This attribute is not writable. |
| </p></blockquote></div> |
