问题现象(使用VS 2008, UNICODE字符集):wfstream f;wstring path = L"C:\\1.txt";f.open( path.c_str(), ios::in);打开文件后,读取文件内容正常,包括中文字符。wofstream f;wstring
int main() { std::string path = ... // insert path to test file here std::ifstream ifs(path.c_str()); if(!ifs) { std::cout << "Failed to open the file." << std::endl; return EXIT_FAILURE; } int n = 0; std::string t; while(!safeGetline(ifs, t).eof()) ++n; ...

每个IO 对象都维护一组条件状态 flags (eofbit, failbit and badbit)，用来指出此对象上是否可以进行 IO 操作。如果遇到错误—例如输入流遇到了文件末尾，则对象的状态变为是失效，所有的后续输入操作都不能执行，直到错误纠正。
