DESCRIPTION

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