	(转)Reading C type declarations
	<p> Even relatively new C programmers have no trouble reading simple C declarations such as </p> <pre class="codeblock"><span class="decl">int foo[5]; </span>// <i>foo is an array of 5 ints</i><br><span class="decl">char foo; </span>// <i>foo is a pointer to char</i><br><span class="decl">double foo(); </span>// <i>foo is a function returning a double</i> </pre> <p> but as the declarations get a bit more involved, it's more difficult to know exactly what you're looking at. </p> <pre class="codeblock"><span class="decl">char ((*foo[][8])())[]; </span>// <i>huh ?????</i> </pre> <p> It turns out that the rules for reading an arbitrarily-complex C variable declaration are easily learned by even beginning programmers (though how to actually <i>use</i> the variable so declared may be well out of reach). </p> <p> This Tech Tip shows how to do it. </p> <h1 id="types">Basic and Derived Types</h1> <p> In addition to one variable n……

	"Portability"
	<h1>What is "Portability"?</h1> <p> The notion of "portability" is widely used, and it's often attached to software inappropriately. Software is only "portable" if it can actually be moved to a <i>different</i> platform, and these are some of the issues that are considered when a port is imminent. </p> <dl class="defnlist"><dt>CPU Architecture Portability </dt><dd>The differences underlying CPU architecture exposes itself in many ways to the C programmer, and these can erupt in surprising and disturbing ways.

	(转)How To Read C Declarations
	<div> <p>Even experienced C programmers have difficulty reading declarations that go beyond simple arrays and pointers. For example, is the following an array of pointers or a pointer to an array?</p> <div class="code"> <div class="codeContent"><pre class="code-java"><span class="code-object">int</span> a[10];</pre></div></div> <p>What the heck does the following mean?</p> <div class="code"> <div class="codeContent"><pre class="code-java"><span class="code-object">int</span> ((*vtable)[])();</pre></div></div> <p>Naturally, it's a <em>pointer to an array of pointers to functions returning integers</em>. <img class="emoticon" alt="" src="http://www.antlr.org/wiki/images/icons/emoticons/wink.gif" align="absmiddle" border="0" height="20" width="20"></p> <p>This short article tells you how to read any C declaration correctly using a very simple technique.

	最令人郁闷的Bug
	今天加了一整天的班就因为两个Bug，郁闷死了。<br>因为将旧项目中的库移植到新的项目中，增加新的功能同时又要向前兼容，本以为编译通过就OK了，结果还是调了一天，总计发现两个bug。一个Bug是因为修改后的代码忘记调用一个初始化函数，导致读取设备状态产生死循环，另一个bug是因为以前修改时直接使用数字而不是宏作为缓冲区的长度，结果结构体长度修改后，缓冲区长度却没变，清缓冲区越界，把其他的数据区也清掉了，导致网络发送死循环。<br>分析起来都是很容易避免的问题，而且这样的错误犯过不止一次，教训惨痛呀。<br><br>时刻牢记教训：<br>1、坚决抵制不可移植的代码；<br>2、使用宏定义常数，不使用显示的数字；<br>3、设备操作不能使用死循环设计，应该采用超时加返回状态的方法检测是否正常；<br>4、函数如果没有被调用就没有存在的必要，删除一切用不到的代码。<br><br>牢记，牢记。<br>
