hi,

how can I replace std::streambuf::setb(...) ?

here is the code that uses it:
void TCPStream::Allocate(int size)
{
        if(size < 2)
        {
                bufsize = 1;
                return;
        }

        gbuf = new char[size];
        pbuf = new char[size];
        if(!pbuf || !gbuf)
        {
                Error(SOCKET_RESOURCE_FAILURE);
                return;
        }
        bufsize = size;
        clear();
        setb(gbuf, gbuf + size, 0);
        setg(gbuf, gbuf + size, gbuf + size);
        setp(pbuf, pbuf + size);
}
