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
whether to do blocking or non-blocking I/O
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.
