Data Structures
struct	LocalMeta2Info
	LocalMeta2Info basically holds all the non server metaserver2 information that we read from the metaserver2 file. More...

Functions
int	count_players ()

bool	metaserver2_config_modified ()
	Return if the metaserver2 file has been modified since last load. More...

void	metaserver2_exit ()
	Stop metaserver updates. More...

int	metaserver2_init (void)
	Initialize metaserver reporting. More...

void	metaserver2_load_config ()

void	metaserver_update (void)
	Updates our info in the metaserver Note that this is used for both metaserver1 and metaserver2 - for metaserver2, it just copies dynamic data into private data structure, doing locking in the process. More...

Variables
static LocalMeta2Info	local_info
	Non volatile information on the server. More...

MetaServer2_UpdateInfo	metaserver2_updateinfo
	Statistics on players and such sent to the metaserver2. More...

static std::thread	metaserver_thread
	Metaserver thread, if notifications are enabled. More...

static std::vector< std::string >	metaservers
	Metaservers to send information to, list of hostnames. More...

static std::mutex	ms2_info_mutex
	Mutex to protect access to metaserver2_updateinfo. More...

static std::timed_mutex	ms2_signal
	When this mutex becomes unlocked, make the metaserver thread exit. More...
