如果把它读入内存再写出，在内存紧张的情况下可能会失败。
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 中已有的，如果它提供这种功能的话。如果你能替我找到，我就更有可能着手实现它。

至于文件复制，为什么要增加对 boost 的依赖？至少我很希望能有一个依赖极少的核心库。
我们在 JSON 以及替代 wxWidgets 依赖的十来处功能中都需要 Boost。Boost 是优秀、可移植的东西，我们不应该回避它。

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.
