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-null 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-null 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.
