Send data to the socket. The socket must be connected to a remote
socket. The optional \var{flags} argument has the same meaning as for
\method{recv()} above. Returns the number of bytes sent.
Applications are responsible for checking that all data has been sent;
if only some of the data was transmitted, the application needs to
attempt delivery of the remaining data.

\begin{methoddesc}[socket]{sendall}{string\optional{, flags}}
Send data to the socket. The socket must be connected to a remote
socket. The optional \var{flags} argument has the same meaning as for
\method{recv()} above. Unlike \method{send()}, this method continues
to send data from \var{string} until either all data has been sent or
an error occurs. \code{None} is returned on success. On error, an
exception is raised, and there is no way to determine how much data,
if any, was successfully sent.
