Prior to this change, the recv call was using the same buflen as that of
the send, which meant that the response would be truncated at by the
client, while the server was sending the entire message. This was
evident by running a Python client which manually called recv with the
maximum buffer size.
This change updates the prototype to take both a bufin (length of the
input buffer), and a bufout (length of the output buffer) argument,
instead of a single buflen. With this change, commands work as expected
in x52ctl.
This change makes X52 daemon listen on a Unix socket. This is in
preparation for changes that will read from the socket and allow clients
to communicate with and control the daemon.
This change adds a library to connect to the X52 daemon and send
commands and receive responses. The library is a thin wrapper around the
POSIX sockets API. While a client could implement the functions
themselves, the library makes it a little bit easier, as well as
allowing for third-party clients to connect to and communicate with the
daemon.
