ASIO 应用层工程组成

ASIO工程目录如下：

• asio:工程文件目录。asio.sln
• common: asiosample.dll和hostsample.exe工程使用的公共文件
• driver: asiosample文件目录
• host: hostsample文件目录

ASIO应用层由asiosample工程和hostsample工程组成。其中：

• hostsample: hostsample.exe
• asiosample: asiosample.dll

hostsample.exe和asiosample.dll有没特别的大的关系。

当然在readme.txt中也有相关的说明：
