BasicOStream is the output stream in the Streams model. It is a std::basic_ostream that holds a BasicStreamBuffer pointer. Insertion uses that buffer through rdbuf(). writesome() writes at most BasicStreamBuffer::out_avail() characters with sputn() and writes nothing when the put area is empty. That is a partial write; it does not block waiting for overflow to flush.
buffer() returns the pointer. setBuffer() replaces it and updates rdbuf(). The stream does not own the buffer.
