Erlang memcached client.


This library is built to be used by the sinan (erlware) build system or other
OTP type releases.  It is a stand-alone OTP application but does not
create/start any gen_servers.  Instead it is to be used as a straight-forward
library.

If you wish to use this library with a gen_server (to keep your memcached
connection) then you can still use this api, you will just need to pass the
socket to the api instead of the host/port connection details.


See docs for full api.  Library includes type and spec attributes for dialyzer.



Usage:

* Store your connection details or pass them straight into the api
1> Connection = {host, "localhost", port, 11211}.


* Set a key/value pair
2> memcached:set(Connection, "key", {ok, "GitHub"}).
ok.


* Retrieve the key/value pair
3> memcached:get(Connection, "key").
[{ok, "GitHub"}]


* Set a key/value pair with flags and timeout of 10 seconds
4> memcached:set(Connection, "github", 0, 10, {url, "http://github.com", author, "asceth", repo, "memcached"}).
ok.


* Retrieve multiple keys
** Results are returned in the order you ask for them, keys that don't exist
** are simply ignored in the returned reply.
5> memcached:get(Connection, ["key", "github"]).
[{ok, "GitHub"}, {url, "http://github.com", author, "asceth", repo, "memcached"}].



* Stats
6> memcached:stats(Connection).
