| |
| <p><a name="index-threads-in-python-1713"></a> |
| <a name="index-gdb_002eInferiorThread-1714"></a>Python scripts can access information about, and manipulate inferior threads |
| controlled by <span class="sc">gdb</span>, via objects of the <code>gdb.InferiorThread</code> class. |
| |
| <p>The following thread-related functions are available in the <code>gdb</code> |
| module: |
| |
| <p><a name="index-gdb_002eselected_005fthread-1715"></a> |
| |
| <div class="defun"> |
| — Function: <b>selected_thread</b><var><a name="index-selected_005fthread-1716"></a></var><br> |
| <blockquote><p>This function returns the thread object for the selected thread. If there |
| is no selected thread, this will return <code>None</code>. |
| </p></blockquote></div> |
| |
| <p>A <code>gdb.InferiorThread</code> object has the following attributes: |
| |
| <dl> |
| |
| <div class="defun"> |
| — Instance Variable of InferiorThread: <b>num</b><var><a name="index-num-1717"></a></var><br> |
| <blockquote> <p>ID of the thread, as assigned by GDB. |
| </p></blockquote></div> |
| |
| <div class="defun"> |
| — Instance Variable of InferiorThread: <b>ptid</b><var><a name="index-ptid-1718"></a></var><br> |
| <blockquote> <p>ID of the thread, as assigned by the operating system. This attribute is a |
| tuple containing three integers. The first is the Process ID (PID); the second |
| is the Lightweight Process ID (LWPID), and the third is the Thread ID (TID). |
| Either the LWPID or TID may be 0, which indicates that the operating system |
| does not use that identifier. |
| </p></blockquote></div> |
| </dl> |
| |
| <p>A <code>gdb.InferiorThread</code> object has the following methods: |
| |
| <dl> |
| |
| <div class="defun"> |
| — Method on InferiorThread: <b>switch</b><var><a name="index-switch-on-InferiorThread-1719"></a></var><br> |
| <blockquote> <p>This changes <span class="sc">gdb</span>'s currently selected thread to the one represented |
| by this object. |
| </p></blockquote></div> |
| |
| <div class="defun"> |
| — Method on InferiorThread: <b>is_stopped</b><var><a name="index-is_005fstopped-on-InferiorThread-1720"></a></var><br> |
| <blockquote> <p>Return a Boolean indicating whether the thread is stopped. |
| </p></blockquote></div> |
| |
| <div class="defun"> |
| — Method on InferiorThread: <b>is_running</b><var><a name="index-is_005frunning-on-InferiorThread-1721"></a></var><br> |
| <blockquote> <p>Return a Boolean indicating whether the thread is running. |
| </p></blockquote></div> |
| |
| <div class="defun"> |
| — Method on InferiorThread: <b>is_exited</b><var><a name="index-is_005fexited-on-InferiorThread-1722"></a></var><br> |
| <blockquote> <p>Return a Boolean indicating whether the thread is exited. |
| </p></blockquote></div> |
