  31 =head1 DESCRIPTION
  32
  33 libmemcached(3) has the ability to query a memcached server (or collection
  34 of servers) for their current state. Queries to find state return a
  35 C<memcached_stat_st> structure. You are responsible for freeing this structure.
  36 While it is possible to access the structure directly it is not advisable.
  37 <memcached_stat_get_value() has been provided to query the structure.
  38
  39 memcached_stat() fetches an array of C<memcached_stat_st> structures containing
  40 the state of all available memcached servers. The return value must be freed
  41 by the calling application.
  42
  43 memcached_stat_servername() can be used standalone without a C<memcached_st> to
  44 obtain the state of a particular server.  "args" is used to define a
  45 particular state object (a list of these are not provided for by either
  46 the memcached_stat_get_keys() call nor are they defined in the memcached
  47 protocol). You must specify the hostname and port of the server you want to
  48 obtain information on.
  49
  50 memcached_stat_get_value() returns the value of a particular state key. You
  51 specify the key you wish to obtain.  The key must be null terminated.
  52
  53 memcached_stat_get_keys() returns a list of keys that the server has state
  54 objects on. You are responsible for freeing this list.
  55
  56 A command line tool, memstat(1), is provided so that you do not have to write
  57 an application to do this.
  58
  59 =head1 RETURN
  60
  61 Varies, see particular functions.
  62
  63 Any method returning a C<memcached_stat_st> expects you to free the
  64 memory allocated for it.
