[data, count] = recv (s, len) ¶[data, count] = recv (s, len, flags) ¶Read data from specified socket.
Requests reading len bytes from the socket s.
The optional integer flags parameter can be used to modify the
behaviour of recv.
The read data is returned in the uint8 array data. The number of bytes read is returned in count.
You can get non-blocking operation by using the flag MSG_DONTWAIT
which makes the recv() call return immediately. If there is no
data, -1 is returned in count.
See the recv man pages for further details.
