The tt(class) ti(filebuf) is a specialization of tt(streambuf) used by the
file ti(stream) classes. Before using a tt(filebuf) the header file
tthi(fstream) must have been included.
In addition to the (public) members that are available through the tt(class
streambuf), tt(filebuf) offers the following (public) members:
itemization(
ithtq(filebuf)(filebuf())
(tt(Filebuf) offers a public constructor. It initializes
a plain tt(filebuf) object that is not yet connected to a stream.)
ithtq(is_open)
(bool is_open())
(tt(True) is returned if the tt(filebuf) is actually connected to an
open file, tt(false) otherwise. See the tt(open) member, below.)
ithtq(open)
(filebuf *open(char const *name, ios::openmode mode))
(This member function associates the tt(filebuf) object with a file
whose name is provided. The file is opened according to the provided
ti(openmode).)
ithtq(close)
(filebuf *close())
(This member function closes the association between the tt(filebuf)
object and its file. The association is automatically closed when the
tt(filebuf) object ceases to exist.)
