  48 DESCRIPTION
  49 -----------
  50
  51 `libmemcached` operates on a list of hosts which are stored in
  52 :type:`memcached_server_st` structures. You should not modify these structures
  53 directly. Functions are provided to modify these structures.
  54
  55 :func:`memcached_server_list` is used to provide an array of all defined hosts.
  56 This was incorrectly documented as "requiring free" up till version 0.39.
  57
  58 :func:`memcached_server_list_free` deallocates all memory associated with the
  59 array of :type:`memcached_server_st` that you passed to it.
  60
  61 :func:`memcached_server_list_append` adds a server to the end of a
  62 :type:`memcached_server_st` array. On error null will be returned and the
  63 :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
  64 port of a memcached server.
  65
  66 DEPRECATED :func:`memcached_servers_parse`, please see :func:`memcached`
  67
  68 :func:`memcached_server_error` can be used to look at the text of the last
  69 error message sent by the server to to the client.
  70
  71 Before version 0.39 theses functions used a memcached_server_st \*. In 0.39
  72 memcached_server_st \* was aliased to :type:`memcached_server_list_st`.
  73 This was done for a style reason to help clean up some concepts in the code.
