[C++] pthread and std::thread区别

So in summary:

• Use pthread if you need maximum portability and control. 更加底层一些？
• Use std::thread if you want an easier to use API and tighter integration with C++. 是对POSIX线程（即pthread）的一个高级封装，提供了更加易用和跨平台的线程支持
• For most C++ programs, I would recommend starting with std::thread. Only drop down to pthreads if you need something std::thread cannot provide.

pthread

Pros:

• Portable (POSIX standard)：POSIX标准是IEEE为在各种UNIX操作系统上运行的软件定义的一系列API标准的总称，定义了Unix系列操作系统对应用的接口规范
• Low level API gives you a lot of control
• Can be used in C programs as well as C++
  Cons:
• Low level API can be cumbersome(笨重) to use
• Lacks some convenient features of std::thread like return values, exceptions, etc. 重要不足
