oeifstream() oeifstream(int fd) oeifstream(const char *filename) oeifstream(const std::string &filename)
Creates a new oeifstream. If a valid file descriptor (fd
) is passed to
the constructor, the stream will use the associated data source for input.
Otherwise, the constructors expect the name of an existing file from which to
read. If no parameter is passed to the constructor, the stream can later be
opened using the open
command defined in OEPlatform::oeistream
or
the openfd
command defined in this class.
