boost里有一个Program_options,在Introduction里写的是The program_options library allows program developers to obtain program options, that is (name, value) pairs from the user, via conventional methods such as command line and config file. 感觉应该能用,花了几个小时读了一下。 结果出乎我的意料,这...

For example, they found that offering fewer sharing options increased the likelihood of customers sharing. "Our program’s performance is constantly improving, and its CPA is consistently cheaper than our other channels. It’s been a game-changer for us." - Diane Larramendy, Chief Operating ...
boost是一个开源的跨平台C++扩展库,曾被称为是C++的准标准库; boost大部分模块都可以通过直接引用头文件来使用,所以使用起来非常方便; 在嵌入式Linux系统下也可以很方便的使用(不用移植编译,直接引用头文件)。 这里的代码是使用boost的bind和function实现的消息处理框架, 用于处理类似“命令字---数据”的消息。 使...
