最近在关注Boost库中智能指针的相关知识，剖析到下面的一段代码，在头文件checked_delete.hpp中的用于释放空间的类模板函
checked_array_delete(T * x)；：

template<class T> inline void checked_array_delete(T * x)  
{  
    typedef char type_must_be_complete[ sizeof(T)? 1: -1 ];  
    (void) sizeof(type_must_be_complete);  
    delete [] x;  
}

代码很简单，但表达的东西却很隐晦，其实这是一种不完全类型检测：T如果不是不完全类型那么sizeof（T）就应该是type_must_be_complete[-1],数组是不能为负数的，所以就会报错；
什么又是不完全类型呢？简单理解就是类型的定义不完整，比如只对类进行了声明，却未定义；

了解单例模式：
实际应用中，有些对象，我们只需要一个就可以了，比如，一台计算机上可以连好几个打印机，但是这个计算机上的打印程序只能有一个，这里就可以通过单例模式来避免两个打印作业同时输出到打印机中，即在整个的打印过程中只有一个打印程序的实例。
单例模式是一种常用的软件设计模式。在它的核心结构中只包含一个被称为单例的特殊类。通过单例模式可以保证系统中一个类只有一个实例。
关于pthread_once
#include <pthread.h>

int pthread_once(pthread_on

看智能指针的时候遇到一组函数蛮有意思的，即checked_delete(T* x)和checked_array_delete(T* x)，这两个函数的作用是安全删除参数所指向的变量或数组。
template inline void checked_delete(T* x)
{
  typedef char type_must_be_complete[ sizeof(T)? 1: -1 ];

检查不完全类型：
举例如下
//BB.h
#include 
  2 class BB
  3 {
  4 public:
  5     BB()
  6     {
  7         std::cout<<"BB"<<std::endl;
  8     }
  9     ~BB()
 10     {
 11         std::cout<<"~BB"<<std::end

__gnu_cxx::new_allocator Simply wraps ::operator new and ::operator delete.

__gnu_cxx::malloc_allocator Simply wraps malloc and free. There is also a hook for an out-of-memory handler

线程存储：Thread Specific Data

线程存储作用
大家都知道，在多线程程序中，所有线程共享进程中的变量。现在有一全局变量，所有线程都可以使用它，改变它的值。而如果每个线程希望能单独拥有它，那么就需要使用线程存储了。
表面上看起来这是一个全局变量，所有线程都可以使用它，而它的值在每一个线程中又是单独存储的。这就是线程存储的意义。
线程存储是实现同一个线程中不同函数间共享数据的一种很好的方式。

线程存储具体用法
创建一个类型为pthread_key_t类型的变量。
调用pthread_key

线程同步四项原则，依照重要性排序：

尽量不要共享对象，共享对象优先选择不可修改的对象
使用高级并发编程构件
使用低级同步原语，只用非递归（不可重入）的互斥量和条件变量，不用读写锁、信号量

吕同学的问题终于解决了，备份以下，顺便分享一下。

 

问题： 在使用boost::scoped_ptr时模板参数使用前置声明类型，编译器报错。

 

前置声明是个好习惯，既可以减少编译依赖，又可以避免循环包含带来的问题，其本身也是最小化原则的体现。

如果你已经把前置声明当作一种习惯而且经常使用boost的智能指针或者曾遇到过类似checked_delete之类的东西，你

在一些编译器中，支持sizeof()返回0，所以，会用到是否为合法类型，否则会导致中断触发

1.初识scoped_ptr

scoped_ptr是一个与auto_ptr/unique_ptr很类似的智能指针，它包装了new操作符在堆上分配的动态对象，能够保证动态创建的对象在任何时候都可以被正确地删除。但scoped_ptr的所有权更加严格，不能转让，一旦scoped_ptr获取了对象的管理权，我们就无法再从它那里收回来。scoped_ptr拥有一个很好的名字，它向代码的阅读者传递了明确的信息：这个智能指针只能在本作用域里使用，不希望被转让。
