mongoc_client_find_databases_with_opts()

mongoc_cursor_t *
mongoc_client_find_databases_with_opts (
   mongoc_client_t *client, const bson_t *opts) BSON_GNUC_WARN_UNUSED_RESULT;


Fetches a cursor containing documents, each corresponding to a database on this MongoDB server.

  • client: A mongoc_client_t.
  • opts: A bson_t containing additional options.

opts may be NULL or a BSON document with additional command options:

  • sessionId: First, construct a mongoc_client_session_t with mongoc_client_start_session. You can begin a transaction with mongoc_client_session_start_transaction, optionally with a mongoc_transaction_opt_t that overrides the options inherited from client, and use mongoc_client_session_append to add the session to opts. See the example code for mongoc_client_session_t.
  • serverId: To target a specific server, include an int32 "serverId" field. Obtain the id by calling mongoc_client_select_server, then mongoc_server_description_id on its return value.

This function is considered a retryable read operation. Upon a transient error (a network error, errors due to replica set failover, etc.) the operation is safely retried once. If retryreads is false in the URI (see mongoc_uri_t) the retry behavior does not apply.

Use mongoc_cursor_error on the returned cursor to check for errors.

A cursor where each result corresponds to the server's representation of a database.

The cursor functions mongoc_cursor_set_limit, mongoc_cursor_set_batch_size, and mongoc_cursor_set_max_await_time_ms have no use on the returned cursor.
