如果读进内存再写出来，在内存紧张时可能会失败。
我在找类似 copyfile(const char* from, const char* to) 或 copyfile(path from, path to) 的东西，最好是 Boost 里现成的。如果你能帮我找到，我更有可能去实现它。

至于文件复制，为什么要增加对 boost 的依赖？我个人希望核心库的依赖越少越好。
我们用 Boost 做 JSON 和十几样取代 wxWidgets 依赖的东西。Boost 是好用、可移植的东西，我们不该回避它。

If you read it into memory and write it out, it could fail in tight memory situations.
I'm looking for something like copyfile(const char* from, const char* to) or copyfile(path from, path to), preferably something in Boost if it has it. If you find it for me, it's more likely I'll get to implementing it.

As for the file copy, why add to the boost dependency? I for one would love to get a core lib with very little deps.
We require Boost for JSON and a dozen things replacing dependencies on wxWidgets. Boost is good, portable stuff, we should not shy away from it.
