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(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  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

       Varies, see particular functions.
