Receive one or more data messages from this in one go.
messages must point to an array of InputMessage structs and
messages.length must be the length of this array. Each InputMessage
contains a pointer to an array of InputVector structs describing the buffers that
the data received in each message will be written to.
flags modify how all messages are received. The commonly available arguments for this are available in the
SocketMsgFlags enum, but the values there are the same as the system values, and
the flags are passed in as-is, so you can pass in system-specific flags too. These flags affect the overall receive operation. Flags affecting
individual messages are returned in flags.
The other members of InputMessage are treated as described in its documentation.
timeout is negative the call will block until
messages.length have been received, the connection is closed
cancellable is cancelled, or an error occurs.
timeout is 0 the call will return up to
messages.length without blocking, or
g_io_error_would_block if no messages are queued in the operating system to be received.
timeout is positive the call will block on the same conditions as if
timeout were negative. If the timeout is
reached before any messages are received, g_io_error_timed_out is returned, otherwise it will return the
number of messages received before timing out. (Note: This is effectively the behaviour of `MSG_WAITFORONE` with
To be notified when messages are available, wait for the g_io_in condition. Note though that you may still receive g_io_error_would_block from receive_messages even if you were previously notified of a g_io_in condition.
If the remote peer closes the connection, any messages queued in the underlying receive buffer will be returned, and subsequent calls to receive_messages will return 0 (with no error set).
On error -1 is returned and throws is set accordingly. An error will only be returned if zero messages could
be received; otherwise the number of messages successfully received before the error will be returned. If
cancellable is cancelled,
g_io_error_cancelled is returned as with any other error.
