Synopsis

#include <rw/bstream.h>

// Construct a RWbostream, using cout's streambuf:

RWbostream bstr(cout);

Description Class

RWbostream

specializes the abstract base class

RWvostream

to store

variables in binary format. The results can be restored by using its counterpart

RWbistream

You can think of it as a binary veneer over an associated

streambuf

. Because

the

RWbostream

retains no information about the state of its associated

streambuf

, its use can be freely exchanged with other users of the streambuf

(such as

ostream

ofstream

Note – Variables should not be separated with whitespace. Such whitespace

would be interpreted literally and would have to be read back in as a character

string.

RWbostream

can be interrogated as to the stream state using member

functions

good(), bad(), eof()

, etc.
