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 ()

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

int	metaserver2_init (void)
	This initializes the metaserver2 logic - it reads the metaserver2 file, storing the values away. More...

void	metaserver2_thread ()
	Repeatedly send updates to the metaserver, stopping when ms2_signal is acquired. More...

static void	metaserver2_updates (void)
	This sends an update to the various metaservers. More...

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...

	Mutex to protect access to metaserver2_updateinfo. More...

◆ metaserver2_exit()

void metaserver2_exit ( )

Stop metaserver updates.

References metaserver_thread, and ms2_signal.

Here is the caller graph for this function:

◆ metaserver2_init()

int metaserver2_init ( void )

This initializes the metaserver2 logic - it reads the metaserver2 file, storing the values away.

Note that it may be possible/desirable for the server to re-read the values and restart connections (for example, a new metaserver has been added and you want to start updates to it immediately and not restart the server). Because of that, there is some extra logic (has_init) to try to take that into account.

Returns: 1 if we will be updating the metaserver, 0 if no metaserver updates
