| void open( const char *filename, ios_base::openmode mode = ios_base::in ); | (1) | |
| void open( const std::string &filename,                                   ios_base::openmode mode = ios_base::in ); | (2) | (since C++11) | 
Opens and associates the file with name filename with the file stream.
Calls setstate(failbit) on failure.
| Calls clear() on success. | (since C++11) | 
1) Effectively calls rdbuf()->open(filename, mode | ios_base::in). (see std::basic_filebuf::open for the details on the effects of that call)
2) Effectively calls (1) as if by open(filename.c_str(), mode).
