return location for a #GSocketAddress, or %NULL
will be set to the number of bytes that have been received
return location for a caller-allocated array of #GSocketControlMessages, or %NULL
collection of #GSocketMsgFlags for the received message, outputted by the call
return location for the number of elements in @control_messages
the number of input vectors pointed to by @vectors
pointer to an array of input vectors
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.
