Hi Claes, +1 to the API style in this new version. My comments (not related to API style) below: - I wonder if the useSecureTransport attribute in UDPCreateOptions is usable for UDPSocket or not, because TLS/SSL is usually used on TCP only. - As for ISSUE 1, I agree with the necessity of an event handler for sending buffer availability. In the case of POSIX socket, if we call send() system call when the buffer is full, it would fail with the error EAGAIN or EWOULDBLOCK, and the select() system call may be used to wait until the buffer becomes available [1]. - I wonder if 'processing' readyState is actually useful or not. IMO it seems to be almost impossible to watch the 'processing' state; if sendUDP() method would simply pass data to the sending buffer, we could immediately know whether the data has been buffered or not. - The maximum length of 'data' parameter in sendUDP() method seems to require discussion. When the length exceeds the maximum length of one UDP payload, there can be two choices: (a) an error would occur, or (b) the data would be separated into segments within the maximum UDP payload size. (POSIX socket follows (a); the error EMSGSIZE would occur.)
