typedef struct _LocalMeta2Info LocalMeta2Info |
LocalMeta2Info basically holds all the non server metaserver2 information that we read from the metaserver2 file. Could just have individual variables, but doing it as a structure is cleaner I think, and might be more flexible if in the future, we want to pass this information to other functions (like plugin or something)
typedef struct _MetaServer2 MetaServer2 |
This is a linked list of all the metaservers - never really know how many we have.

This frees any data associated with the MetaServer2 info, including the pointer itself. Caller is responsible for updating pointers (ms->next) - really only used when wanting to free all data.
ms | data to free, pointer becomes invalid. |

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.

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.
junk | unused. |

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

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.
ptr | actual data. |
size | size of the data. |
nmemb | number of elements. |
data | user-provided data, unused. |

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.
