basic_ofstream::open

Opens a file.

void open(
    const char *_Filename,
    ios_base::openmode _Mode = ios_base::out,
    int _Prot = (int)ios_base::_Openprot
);
void open(
    const char *_Filename,
    ios_base::openmode _Mode
);
void open(
    const wchar_t *_Filename,
    ios_base::openmode _Mode = ios_base::out,
    int _Prot = (int)ios_base::_Openprot
);
void open(
    const wchar_t *_Filename,
    ios_base::openmode _Mode
);

_Filename

The name of the file to open.

_Mode

One of the enumerations in ios_base::openmode.

_Prot

The default file opening protection, equivalent to the shflag parameter in _fsopen, _wfsopen.

The member function calls rdbuf -> open(_Filename, _Mode | ios_base::out). If that function returns a null pointer, the function calls setstate(failbit).

See basic_filebuf::open for an example that uses open.
