libmemcached(3) performs operations on a list of hosts. The order of these hosts determine routing to keys. Functions are provided to add keys to memcached_st structures. To manipulate lists of servers see memcached_server_st(3).
memcached_server_count() provides you a count of the current number of servers being used by a "memcached_st" structure.
memcached_server_add() pushes a single TCP server into the "memcached_st" structure. This server will be placed at the end. Duplicate servers are allowed, so duplication is not checked. Executing this function with the "MEMCACHED_BEHAVIOR_USE_UDP" behavior set will result in a "MEMCACHED_INVALID_HOST_PROTOCOL".
memcached_server_add_udp() pushes a single UDP server into the "memcached_st" structure. This server will be placed at the end. Duplicate servers are allowed, so duplication is not checked. Executing this function with out setting the "MEMCACHED_BEHAVIOR_USE_UDP" behavior will result in a "MEMCACHED_INVALID_HOST_PROTOCOL".
memcached_server_add_unix_socket() pushes a single UNIX socket into the "memcached_st" structure. This UNIX socket will be placed at the end. Duplicate servers are allowed, so duplication is not checked. The length of the filename must be one character less then MEMCACHED_MAX_HOST_LENGTH.
memcached_server_push() pushes an array of "memcached_server_st" into the "memcached_st" structure. These servers will be placed at the end. Duplicate servers are allowed, so duplication is not checked. A copy is made of structure so the list provided (and any operations on the list) are not saved.
memcached_server_by_key() allows you to provide a key and retrieve the server which would be used for assignment. This structure is cloned from its original structure and must be freed. If NULL is returned you should consult *error. The returning structure should be freed with memcached_server_free().
memcached_server_get_last_disconnect() returns a pointer to the last server for which there was a connection problem. It does not mean this particular server is currently dead but if the library is reporting a server is, the returned server is a very good candidate.
memcached_server_cursor() takes a memcached_st and loops through the list of hosts currently in the cursor calling the list of callback functions provided. You can optionally pass in a value via context which will be provided to each callback function. An error return from any callback will terminate the loop. memcached_server_cursor() is passed the original caller memcached_st in its current state.
Varies, see particular functions.
