filebuf
A type basic_filebuf specialized on char template parameters.
typedef basic_filebuf<char, char_traits<char>> filebuf;
Remarks
The type is a synonym for template class basic_filebuf, specialized for elements of type char with default character traits.
fstream
A type basic_fstream specialized on char template parameters.
typedef basic_fstream<char, char_traits<char>> fstream;
Remarks
The type is a synonym for template class basic_fstream, specialized for elements of type char with default character traits.
ifstream
Defines a stream to be used to read single-byte character data serially from a file. ifstream is a typedef that specializes the template class basic_ifstream for char.
There is also wifstream, a typedef that specializes basic_ifstream to read wchar_t double-wide characters. For more information, see wifstream.
typedef basic_ifstream<char, char_traits<char>> ifstream;
Remarks
The type is a synonym for template class basic_ifstream, specialized for elements of type char with default character traits. An example is
using namespace std;
ifstream infile("existingtextfile.txt");
if (!infile.bad())
{
// Dump the contents of the file to cout.
cout << infile.rdbuf();
infile.close();
}
ofstream
A type basic_ofstream specialized on char template parameters.
typedef basic_ofstream<char, char_traits<char>> ofstream;
Remarks
The type is a synonym for template class basic_ofstream, specialized for elements of type char with default character traits.
wfstream
A type basic_fstream specialized on wchar_t template parameters.
typedef basic_fstream<wchar_t, char_traits<wchar_t>> wfstream;
Remarks
The type is a synonym for template class basic_fstream, specialized for elements of type wchar_t with default character traits.
wifstream
A type basic_ifstream specialized on wchar_t template parameters.
typedef basic_ifstream<wchar_t, char_traits<wchar_t>> wifstream;
Remarks
The type is a synonym for template class basic_ifstream, specialized for elements of type wchar_t with default character traits.
wofstream
A type basic_ofstream specialized on wchar_t template parameters.
typedef basic_ofstream<wchar_t, char_traits<wchar_t>> wofstream;
Remarks
The type is a synonym for template class basic_ofstream, specialized for elements of type wchar_t with default character traits.
wfilebuf
A type basic_filebuf specialized on wchar_t template parameters.
typedef basic_filebuf<wchar_t, char_traits<wchar_t>> wfilebuf;
Remarks
The type is a synonym for template class basic_filebuf, specialized for elements of type wchar_t with default character traits.
