如果你把它读进内存再写出去,在内存紧张的情况下可能会失败。
If you read it into memory and write it out, it could fail in tight memory situations.
我在找类似 copyfile(const char* from, const char* to) 或 copyfile(path from, path to) 的东西,最好 Boost 里就有。如果你能帮我找到,我就更有可能动手实现它。
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.
