Detailed Description

Special types and wrappers used in the Socket::sendMessage() and Socket::receiveMessage() APIs.

These APIs are pretty complex as they allow a lot of different system call configurations and also control messages to be passed. The struct msghdr behaves quite differently when used for sending as compared to when used for receiving. For this reason we provide different wrappers for both purposes.
