Receive data (up to size bytes) from a socket. This is mainly used by
connection-oriented sockets; it is identical to g_socket_receive_from()
with address set to NULL.
For G_SOCKET_TYPE_DATAGRAM and G_SOCKET_TYPE_SEQPACKET sockets,
g_socket_receive() will always read either 0 or 1 complete messages from
the socket. If the received message is too large to fit in buffer, then
the data beyond size bytes will be discarded, without any explicit
indication that this has occurred.
For G_SOCKET_TYPE_STREAM sockets, g_socket_receive() can return any
number of bytes, up to size. If more than size bytes have been
received, the additional data will be returned in future calls to
g_socket_receive().
If the socket is in blocking mode the call will block until there is
some data to receive or there is an error. If there is no data available
and the socket is in non-blocking mode, a G_IO_ERROR_WOULD_BLOCK error
will be returned. To be notified when data is available, wait for the
G_IO_IN condition.
On error -1 is returned and error is set accordingly.
