=head1 NAME
memcached_stat, memcached_stat_servername, memcached_stat_get_value, memcached_stat_get_keys - Get memcached statistics
=head1 LIBRARY
C Client Library for memcached (libmemcached, -lmemcached)

const char *hostname,
unsigned int port);
char *
memcached_stat_get_value (memcached_st *ptr,
memcached_stat_st *stat,
const char *key,
memcached_return_t *error);
char **
memcached_stat_get_keys (memcached_st *ptr,
memcached_stat_st *stat,
memcached_return_t *error);
=head1 DESCRIPTION
libmemcached(3) has the ability to query a memcached server (or collection
of servers) for their current state. Queries to find state return a
C<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() fetches an array of C<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 C<MEMCACHED_BEHAVIOR_USE_UDP>
behavior set, a NULL value is returned and the error parameter is set to
C<MEMCACHED_NOT_SUPPORTED>.
memcached_stat_servername() can be used standalone without a C<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.
=head1 RETURN
Varies, see particular functions.
Any method returning a C<memcached_stat_st> expects you to free the
memory allocated for it.
