用C++的fstream实现文件拷贝的简单方法

bool DuplicateFile(const char* psrc, const char* pdest){if (NULL == psrc || NULL == pdest)return false;std::fstream src(psrc, std::ios::in | std::ios::binary);std::fstream dest(pdest, std::ios::out | std::ios::binary);if (!src.good() || !dest.good())return false;char ch = 0;while (src.get(ch))dest.put(ch);src.close();dest.close();return true;}
