DESCRIPTION

       libmemcached 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.

       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  without  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 than
       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.

       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.

RETURN VALUE

       Varies, see particular functions.
