libmemcached(3) has the ability to query a memcached server (or collection 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 argument 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 containing the state of all available memcached servers. The return value must be freed by the calling application. If called with the MEMCACHED_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 memcached_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 terminated. \%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.
