  34 DESCRIPTION
  35 -----------
  36
  37
  38 libmemcached(3) operates on a list of hosts which are stored in
  39 :c:type:`memcached_server_st` structures. You should not modify these structures
  40 directly. Functions are provided to modify these structures (and more can be
  41 added, just ask!).
  42
  43 :c:func:`memcached_server_list()` is used to provide an array of all defined hosts. This was incorrectly documented as "requiring free()" up till version 0.39.
  44
  45 :c:func:`memcached_server_list_free()` deallocates all memory associated with the array of :c:type:`memcached_server_st` that you passed to it.
  46
  47 :c:func:`memcached_server_list_append()` adds a server to the end of a
  48 :c:type:`memcached_server_st` array. On error null will be returned and the
  49 :c:type:`memcached_return_t` pointer you passed into the function will be set with the appropriate error. If the value of port is zero, it is set to the default
  50 port of a memcached server.
  51
  52 DEPRECATED :c:func:`memcached_servers_parse()`, please see :c:func:`memcached()`
  53
  54 :c:func:`memcached_server_error()` can be used to look at the text of the last error message sent by the server to to the client.
  55
  56 Before version 0.39 theses functions used a memcache_server_st \*. In 0.39
  57 memcached_server_st \* was aliased to :c:type:`memcached_server_list_st`. This was done for a style reason to help clean up some concepts in the code.
