抱歉，我最近太忙了，消息只能粗看，还是跟不上。
我们要尽量避免 Windows API 调用。它们通常要 6-8 个参数，还要大量测试才能写对，做件简单的事得写一页代码。
我通常也回避 iostreams。感觉经常碰到它的局限。90 年代他们把 C++ 流标准搞砸了，挺可惜的，流做好了可以非常强大好用。在 rpc.cpp 里用它，没准还是个错误。
归根结底，我宁愿调用现成的文件复制函数，也不愿自己写一个再测试。

Sorry, I've been so busy lately I've been skimming messages and I still can't keep up.
We want to avoid Windows API calls whenever possible. They usually take about 6-8 parameters and a lot of testing to get right, it takes a page of code to do something simple.
I usually shy away from iostreams. Seems like I too often hit limitations. They kind of botched the C++ streams standard in the 90's, which is too bad, streams can be very powerful and useful when done right. Using it in rpc.cpp may still turn out to be a mistake.
Bottom line is I'd rather call an existing file copy function than make and test my own.
