SYNOPSIS

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

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

       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.

PARAMETERS

       • client: A mongoc_client_t <>.

       • opts: A bson_t <https://www.mongoc.org/libbson/current/bson_t.html> 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.

       For a list of all options, see the MongoDB Manual entry on the listDatabases command <https://www.mongodb
       .com/docs/manual/reference/command/listDatabases/>.

ERRORS

       Use mongoc_cursor_error() <> on the returned cursor to check for errors.

RETURNS

       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.
