Syntax

#include <fstream>

filebuf	A type `basic_filebuf` specialized on `char` template parameters.
fstream	A type `basic_fstream` specialized on `char` template parameters.
ifstream	A type `basic_ifstream` specialized on `char` template parameters.
ofstream	A type `basic_ofstream` specialized on `char` template parameters.
wfstream	A type `basic_fstream` specialized on `wchar_t` template parameters.
wifstream	A type `basic_ifstream` specialized on `wchar_t` template parameters.
wofstream	A type `basic_ofstream` specialized on `wchar_t` template parameters.
wfilebuf	A type `basic_filebuf` specialized on `wchar_t` template parameters.

basic_filebuf	The template class describes a stream buffer that controls the transmission of elements of type Elem, whose character traits are determined by the class Tr, to and from a sequence of elements stored in an external file.
basic_fstream	The template class describes an object that controls insertion and extraction of elements and encoded objects using a stream buffer of class basic_filebuf<Elem, Tr>, with elements of type Elem, whose character traits are determined by the class Tr.
basic_ifstream	The template class describes an object that controls extraction of elements and encoded objects from a stream buffer of class basic_filebuf<Elem, Tr>, with elements of type Elem, whose character traits are determined by the class Tr.
basic_ofstream	The template class describes an object that controls insertion of elements and encoded objects into a stream buffer of class basic_filebuf<Elem, Tr>, with elements of type Elem, whose character traits are determined by the class Tr.
