       libmemcached(3) has the ability to query a memcached server (or collec-
       tion  of servers) for their current state. Queries to find state return
       a memcached_stat_st structure. You are  responsible  for  freeing  this
       structure.  While it is possible to access the structure directly it is
       not advisable. memcached_stat_get_value() has been  provided  to  query
       the structure.

       memcached_stat_execute()  uses  the  servers found in memcached_stat_st
       and executes a "stat" command on each server. args is an optional argu-
       ment  that can be passed in to modify the behavior of "stats". You will
       need to supply a callback function that will be supplied each  pair  of
       values returned by the memcached server.

       memcached_stat()  fetches an array of memcached_stat_st structures con-
       taining the state of all available memcached servers. The return  value
       must  be  freed  by  the  calling  application. If called with the MEM-
       CACHED_BEHAVIOR_USE_UDP behavior set, a NULL value is returned and  the
       error parameter is set to MEMCACHED_NOT_SUPPORTED.

       memcached_stat_servername()  can  be  used  standalone  without  a mem-
       cached_st to obtain the state of a particular server.  "args"  is  used
       to  define  a particular state object (a list of these are not provided
       for by either the memcached_stat_get_keys() call nor are  they  defined
       in  the  memcached protocol). You must specify the hostname and port of
       the server you want to obtain information on.

       memcached_stat_get_value() returns the value of a particular state key.
       You  specify  the  key you wish to obtain.  The key must be null termi-

       memcached_stat_get_keys() returns a list of keys that  the  server  has
       state objects on. You are responsible for freeing this list.

       A command line tool, memstat(1), is provided so that you do not have to
       write an application to do this.

       Varies, see particular functions.

       Any method returning a memcached_stat_st expects you to free the memory
       allocated for it.
