writing memcached connection using pecl based memcached extension

Question

I am actually thinking to start using memcached in my php code,

http://us3.php.net/manual/en/book.memcached.php

while I searched in google, I find memcache based examples, but not much about memcached based connection and other examples.

it will be really helpful, if someone can share procedural way of writing memcached connection for php memcached (libmemcached based) extension, thank you
