=> R0 = Socket descriptor

This SWI was introduced with Internet 5.00 and should be used in preference to Socket_Recvfrom.
This call has identical functionality to Socket_Recv and recv() except that the address of the host that sent the data will be returned in the block supplied. If no data is available, the call will block until data is available, unless the socket has been marked non-blocking, in which case -1 will be returned and errno set to EWOULDBLOCK.
