memcached_dump - libmemcached Documentation

memcached_dump() is used to get a list of keys found in memcached(1) servers. Because memcached does not guarantee to dump all keys you can not assume you have fetched all keys from the server. The function takes an array of callbacks that it will use to execute on keys as they are found. Currently the binary protocol is not tested.

A value of type memcached_return_t is returned. On success that value will be MEMCACHED_SUCCESS. Use memcached_strerror() to translate this value to a printable string.
