NAME
memcached_stat_execute - libmemcached Documentation Get memcached statistics SYNOPSIS
#include <libmemcached/memcached.h> memcached_stat_st memcached_return_t (*memcached_stat_fn)(memcached_server_instance_st server, const char *key, size_t key_length, const char *value, size_t value_length, void *context) memcached_stat_st *memcached_stat(memcached_st *ptr, char *args, memcached_return_t *error) memcached_return_t memcached_stat_servername(memcached_stat_st *stat, char *args, const char *hostname, in_port_t 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) memcached_return_t memcached_stat_execute(memcached_st *memc, const char *args, memcached_stat_fn func, void *context) Compile and link with -lmemcached 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 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 ter- minated. 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. RETURN
Varies, see particular functions. Any method returning a memcached_stat_st expects you to free the memory allocated for it. HOME
