=head1 DESCRIPTION
libmemcached(3) 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 C<memcached_st> structure.
memcached_server_list() is used to provide an array of all defined hosts.
You are responsible for freeing this list (aka it is not a pointer to the
currently used structure).
memcached_server_add() pushes a single TCP server into the C<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
C<MEMCACHED_BEHAVIOR_USE_UDP> behavior set will result in a
C<MEMCACHED_INVALID_HOST_PROTOCOL>.
memcached_server_add_udp() pushes a single UDP server into the C<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 C<MEMCACHED_BEHAVIOR_USE_UDP> behavior will result in a
C<MEMCACHED_INVALID_HOST_PROTOCOL>.
memcached_server_add_unix_socket() pushes a single UNIX socket into the
C<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 then MEMCACHED_MAX_HOST_LENGTH.
memcached_server_push() pushes an array of C<memcached_server_st> into
the C<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. This structure is cloned
from its original structure and must be freed. If NULL is returned you
should consult *error. The returning structure should be freed with
memcached_server_free().
=head1 RETURN
Varies, see particular functions.
