Overview

Structure used for scatter/gather data input when receiving multiple messages or packets in one go. You generally pass in an array of empty #GInputVectors and the operation will use all the buffers as if they were one buffer, and will set bytes_received to the total number of bytes received across all #GInputVectors.

This structure closely mirrors struct mmsghdr and struct msghdr from the POSIX sockets API (see man 2 recvmmsg).

If address is non-nil then it is set to the source address the message was received from, and the caller must free it afterwards.

If control_messages is non-nil then it is set to an array of control messages received with the message (if any), and the caller must free it afterwards. num_control_messages is set to the number of elements in this array, which may be zero.

Flags relevant to this message will be returned in flags. For example, MSG_EOR or MSG_TRUNC.
