  11 The Threads Window</h1>
  12 <p>The threads window is displayed using <i>View|Threads</i>. The threads
  13 window lists the active threads of the program.</p>
  14 <p><b><i>Note:</i></b> Debugging threaded programs must be supported by
  15 the version of gdb that is used - it is not a feature of KDbg. For Linux
  16 systems this works best with gdb5 and later. However, at the time of this writing gdb
  17 still poorly supports threads on NPTL- (New Posix Threads Library) enabled
  18 systems (glibc 2.3.x and kernel 2.6.x).</p>
  19 <p>The contents of the threads window are updated every time the program
  20 is stopped by the debugger. (That is, the window does <em>not</em> reflect
  21 the state while the program is running.)</p>
  22 <p>The first column shows the thread ID, the second column identifies the
  23 location where the thread currently executes.</p>
  24 <p>The marker in front of the line tells which thread currently is <em>active</em>:</p>
  25 <ul>
  26 <li>
  27 The <a href="stack.html">stack window</a> displays the active threads's
  28 backtrace.</li>
  29
  30 <li>
  31 The <a href="localvars.html">local variables</a> window displays the active
  32 thread's local variables.</li>
  33
  34 <li>
  35 The <a href="watches.html">watch window</a> uses the active thread's local
  36 variables to evaluate the expressions.</li>
  37 </ul>
  38 <p>By clicking a listed thread, the active thread is switched, and the corresponding
  39 windows are updated. In particular, the <a href="sourcecode.html">source
  40 window</a> displays the location where the active thread is currently halted.</p>
