40 libmemcached performs operations on a list of hosts. The order of these
41 hosts determine routing to keys. Functions are provided to add keys to
42 memcached_st structures. To manipulate lists of servers see mem‐
43 cached_server_st(3).
44
45 memcached_server_count() provides you a count of the current number of
46 servers being used by a memcached_st structure.
47
48 memcached_server_add() pushes a single TCP server into the memcached_st
49 structure. This server will be placed at the end. Duplicate servers
50 are allowed, so duplication is not checked. Executing this func‐
51 tion with the MEMCACHED_BEHAVIOR_USE_UDP behavior set will
52 result in a MEMCACHED_INVALID_HOST_PROTOCOL.
53
54 memcached_server_add_udp() pushes a single UDP server into the mem‐
55 cached_st structure. This server will be placed at the end. Duplicate
56 servers are allowed, so duplication is not checked. Executing this
57 function with out setting the MEMCACHED_BEHAVIOR_USE_UDP behavior will
58 result in a MEMCACHED_INVALID_HOST_PROTOCOL.
59
60 memcached_server_add_unix_socket() pushes a single UNIX socket into the
61 memcached_st structure. This UNIX socket will be placed at the end.
62 Duplicate servers are allowed, so duplication is not checked. The
63 length of the filename must be one character less than MEM‐
64 CACHED_MAX_HOST_LENGTH.
65
66 memcached_server_push() pushes an array of memcached_server_st into the
67 memcached_st structure. These servers will be placed at the end. Dupli‐
68 cate servers are allowed, so duplication is not checked. A copy is made
69 of structure so the list provided (and any operations on the list) are
70 not saved.
71
72 memcached_server_by_key() allows you to provide a key and retrieve the
73 server which would be used for assignment.
74
75 memcached_server_get_last_disconnect() returns a pointer to the last
76 server for which there was a connection problem. It does not mean this
77 particular server is currently dead but if the library is reporting a
78 server is, the returned server is a very good candidate.
79
80 memcached_server_cursor() takes a memcached_st and loops through the
81 list of hosts currently in the cursor calling the list of callback
82 functions provided. You can optionally pass in a value via context
83 which will be provided to each callback function. An error return from
84 any callback will terminate the loop. memcached_server_cursor() is
85 passed the original caller memcached_st in its current state.

88 Varies, see particular functions.
