60 .SH DESCRIPTION
61 .sp
62 libmemcached(3) has the ability to query a memcached server (or collection
63 of servers) for their current state. Queries to find state return a
64 \fBmemcached_stat_st\fP structure. You are responsible for freeing this structure.
65 While it is possible to access the structure directly it is not advisable.
66 <memcached_stat_get_value() has been provided to query the structure.
67 .sp
68 memcached_stat_execute() uses the servers found in \fBmemcached_stat_st\fP and
69 executes a "stat" command on each server. args is an optional argument that
70 can be passed in to modify the behavior of "stats". You will need to supply
71 a callback function that will be supplied each pair of values returned by
72 the memcached server.
73 .sp
74 memcached_stat() fetches an array of \fBmemcached_stat_st\fP structures containing
75 the state of all available memcached servers. The return value must be freed
76 by the calling application. If called with the \fBMEMCACHED_BEHAVIOR_USE_UDP\fPbehavior set, a NULL value is returned and the error parameter is set to
77 \fBMEMCACHED_NOT_SUPPORTED\fP.
78 .sp
79 memcached_stat_servername() can be used standalone without a \fBmemcached_st\fP to
80 obtain the state of a particular server. "args" is used to define a
81 particular state object (a list of these are not provided for by either
82 the memcached_stat_get_keys() call nor are they defined in the memcached
83 protocol). You must specify the hostname and port of the server you want to
84 obtain information on.
85 .sp
86 memcached_stat_get_value() returns the value of a particular state key. You
87 specify the key you wish to obtain. The key must be null terminated.
88 .sp
89 memcached_stat_get_keys() returns a list of keys that the server has state
90 objects on. You are responsible for freeing this list.
91 .sp
92 A command line tool, memstat(1), is provided so that you do not have to write
93 an application to do this.
94 .SH RETURN
95 .sp
96 Varies, see particular functions.
97 .sp
98 Any method returning a \fBmemcached_stat_st\fP expects you to free the
99 memory allocated for it.
