Detailed Description

IOStream is the connection after an HTTP upgrade, not the body of a request or reply. Service::upgradeRequested() provides it, and WebSocket::accept() takes it.

peeksome()

std::streamsize peeksome ( char * buffer, std::streamsize n )

inherited

The number of bytes that can be peeked depends on the current stream buffer get area and maybe less than requested, similar to istream::readsome().
