a buffer to read data into (which should be at least size bytes long). [array length=size][element-type guint8]
the number of bytes you want to read from the socket
a GCancellable or NULL. [allow-none]
Number of bytes read, or 0 if the connection was closed by the peer, or -1 on error
GException on failure.
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, the connection is closed, 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. Since 2.22
