| 30 | Because the TIB (thread information block) is not fully described in the | |
| 31 | MSDN, it might be possible that not all required TIB-parts are swapped. With | |
| 32 | compiler flag <code class="computeroutput"><span class="identifier">BOOST_USE_WINFIBERS</span></code> | |
| 33 | <code class="computeroutput"><span class="identifier">execution_context</span></code> uses internally | |
| 34 | the Windows Fiber API. | |

| 42 | The first call of <code class="computeroutput"><span class="identifier">execution_context</span><span class="special">::</span><span class="keyword">operator</span><span class="special">()</span></code> converts the thread into a Windows fiber | |

If desired, <code class="computeroutput"><span class="identifier">ConvertFiberToThread</span><span class="special">()</span></code> has to be called by the user explicitly | |
| 44 | in order to release resources allocated by <code class="computeroutput"><span class="identifier">ConvertThreadToFiber</span><span class="special">()</span></code> (e.g. after using boost.context). | |
