int count_players ( )

◆ 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

◆ metaserver2_thread()

void* metaserver2_thread ( void *  junk)

metserver2_thread is the function called from pthread_create. it is a trivial function - it just sleeps and calls the update function. The sleep time here is really quite arbitrary, but once a minute is probably often enough. A better approach might be to do a time() call and see how long the update takes, and sleep according to that.

Parameters
junkunused.
Returns
This function should never return/exit.

This sends an update to the various metaservers. It generates the form, and then sends it to the server

◆ metaserver2_writer()

static size_t metaserver2_writer ( void *  ptr,
size_t  size,
size_t  nmemb,
void *  data 
)
static

Handles writing of HTTP request data from the metaserver2. We treat the data as a string. We should really pay attention to the header data, and do something clever if we get 404 codes or the like.

Parameters
ptractual data.
sizesize of the data.
nmembnumber of elements.
datauser-provided data, unused.
Returns
number of bytes processed, always the full size.

◆ metaserver_update()

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.
