RWpistream pstr(cin); // Construct an RWpistream, using cin's
// streambuf
Description
Class RWpistream specializes the abstract base class RWvistream to restore variables stored in a
portable ASCII format by RWpostream.
You can think of RWpistream and RWpostream as an ASCII veneer over an associated
streambuf which are responsible for formatting variables and escaping characters such that the
results can be interchanged between any machines. As such, they are slower than their binary
counterparts RWbistream and RWbostream which are more machine dependent. Because
RWpistream and RWpostream retain no information about the state of their associated
streambufs, their use can be freely exchanged with other users of the streambuf (such as
istream or ifstream).
RWpistream can be interrogated as to the stream state using member functions good(), bad(),
eof(), etc.
