<h2>13.2. unsafe.Pointer</h2>
|
||||
<p>大多数指针类型会写成<code>*T</code>，表示是“一个指向T类型变量的指针”。unsafe.Pointer是特别定义的一种指针类型（译注：类似C语言中的<code>void*</code>类型的指针），它可以包含任意类型变量的地址。当然，我们不可以直接通过<code>*p</code>来获取unsafe.Pointer指针指向的真实变量的值，因为我们并不知道变量的具体类型。和普通指针一样，unsafe.Pointer指针也是可以比较的，并且支持和nil常量比较判断是否为空指针。</p>

<h2>13.3. 示例: 深度相等判断</h2>
|
||||
<p>来自reflect包的DeepEqual函数可以对两个值进行深度相等判断。DeepEqual函数使用内建的==比较操作符对基础类型进行相等判断，对于复合类型则递归该变量的每个基础类型然后做类似的比较判断。因为它可以工作在任意的类型上，甚至对于一些不支持==操作运算符的类型也可以工作，因此在一些测试代码中广泛地使用该函数。比如下面的代码是用DeepEqual函数比较两个字符串slice是否相等。</p>

<h2>13.4. 通过cgo调用C代码</h2>
|
||||
<p>Go程序可能会遇到要访问C语言的某些硬件驱动函数的场景，或者是从一个C++语言实现的嵌入式数据库查询记录的场景，或者是使用Fortran语言实现的一些线性代数库的场景。C语言作为一个通用语言，很多库会选择提供一个C兼容的API，然后用其他不同的编程语言实现（译者：Go语言需要也应该拥抱这些巨大的代码遗产）。</p>
