本文探讨了如何在C++中根据不同操作系统包含不同的头文件，并推荐了一种标准化的方法来组织平台特定的代码，包括使用预处理器指令和选择平台独立的库。

How do i include different headers based on my OS?

with preprocessor:

#ifdef _SUNOS
//code
#elseif _LINUX
//code
#elseif _HPUX
//code
#elseif _WIN32
//code
#else
#error OS not supported
#endif

What is the recommended way to organize platform specific code in C++?

Stick to standards defined by C++ ISO specifications.
Use PLATFORM independent libraries (like Boost and Qt and Fltk)
Make sure you don't use COMPILER specific extensions, or atleast stick to 1 SINGLE compiler(recommended: G++ which is cross platform)

Follow these first. Patterns are but means of organising code. Standard patterns allowed by a language theoretically remain the same across all platforms, so that shouldn't be a part of the problem
Use #ifdef MACROS to code platform specific path to files, platform specific libraries for networking etc
