seqdev
Class
seqdev
is a base class that represents the interface to an arbitrary
sequential device. It is almost an abstract base class, except we
define default member functions that do nothing and always return failure
(EOF
). This makes it easy to derive a class that can do input (or output)
only. seqbuf
is derived from seqdev
. To create a functioning
streambuf
, "mixin" an implementation of seqdev
in with seqbuf
.
