- Not many changes here to <code class="filename">cstdlib</code>. You should note that the |
- <code class="function">abort()</code> function does not call the |
- destructors of automatic nor static objects, so if you're |
- depending on those to do cleanup, it isn't going to happen. |
- (The functions registered with <code class="function">atexit()</code> |
- don't get called either, so you can forget about that |
- possibility, too.) |
- </p><p> |
- The good old <code class="function">exit()</code> function can be a bit |
- funky, too, until you look closer. Basically, three points to |
- remember are: |
- </p><div class="orderedlist"><ol type="1"><li><p> |
- Static objects are destroyed in reverse order of their creation. |
- </p></li><li><p> |
- Functions registered with <code class="function">atexit()</code> are called in |
- reverse order of registration, once per registration call. |
- (This isn't actually new.) |
- </p></li><li><p> |
- The previous two actions are “<span class="quote">interleaved,</span>” that is, |
- given this pseudocode: |
- </p><pre class="programlisting"> |
- extern "C or C++" void f1 (void); |
- extern "C or C++" void f2 (void); |
- |
- static Thing obj1; |
- atexit(f1); |
- static Thing obj2; |
- atexit(f2); |
-</pre><p> |
- then at a call of <code class="function">exit()</code>, |
- <code class="varname">f2</code> will be called, then |
- <code class="varname">obj2</code> will be destroyed, then |
- <code class="varname">f1</code> will be called, and finally |
- <code class="varname">obj1</code> will be destroyed. If |
- <code class="varname">f1</code> or <code class="varname">f2</code> allow an |
- exception to propagate out of them, Bad Things happen. |
- </p></li></ol></div><p> |
- Note also that <code class="function">atexit()</code> is only required to store 32 |
- functions, and the compiler/library might already be using some of |
- those slots. If you think you may run out, we recommend using |
- the <code class="function">xatexit</code>/<code class="function">xexit</code> combination from <code class="literal">libiberty</code>, which has no such limit. |
