<p>首先，对于每个以非空析构器创建，关联值非空的（见 <span class="t-lc"><a href="c-thread-tss_create.html">tss_create</a></span> ）线程特定存储关键， <code>thrd_exit</code> 设置与关键关联的值为 <span class="t-c"><span class="mw-geshi c source-c"><a href="c-types-NULL.html"><span class="kw103">NULL</span></a></span></span> ，然后以该关键的先前值调用析构器。析构器的调用顺序是未指定的。</p>
|
|
<p>若在此后，有剩余关键拥有非空的析构器和值（例如若析构器执行了 <span class="t-lc"><a href="c-thread-tss_set.html">tss_set</a></span> ），则至多重复 <span class="t-lc"><a href="c-thread-TSS_DTOR_ITERATIONS.html">TSS_DTOR_ITERATIONS</a></span> 次处理。</p>
|
|
<p>最后， <code>thrd_exit</code> 函数终止调用方线程的执行，并设置其结果码为 <code>res</code> 。</p>
|
|
<p>若程序中的最后线程以 <code>thrd_exit</code> 退出，则如同通过以 <span class="t-lc"><a href="c-program-EXIT_status.html">EXIT_SUCCESS</a></span> 为参数调用 <span class="t-lc"><a href="c-program-exit.html">exit</a></span> 一般终止整个程序（故 <span class="t-lc"><a href="c-program-atexit.html">atexit</a></span> 所注册的函数在最后线程的环境中执行）。</p>
