SYNOPSIS

10          mongoc_server_description_t **
11          mongoc_client_get_server_descriptions (const mongoc_client_t *client,
12                                                 size_t *n);
13
14       Fetches an array of mongoc_server_description_t structs for  all  known
15       servers  in the topology. Returns no servers until the client connects.
16       Returns a single server if the client is  directly  connected,  or  all
17       members of a replica set if the client's MongoDB URI includes a "repli‐
18       caSet" option, or all known mongos servers if the MongoDB URI  includes
19       a list of them.
