mongoc_bulkwritereturn_t is returned by mongoc_bulkwrite_execute().

       res or exc may outlive the mongoc_bulkwrite_t that was executed.

       res  is  NULL  if  the  mongoc_bulkwrite_t  has  no  known  successful  writes  or  was  executed with an
       unacknowledged write concern.

       res must be freed with mongoc_bulkwriteresult_destroy().

       exc is NULL if no error occurred.

       exc must be freed with mongoc_bulkwriteexception_destroy().
