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 MEM-
       CACHED_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.
