          mongoc_socket_recv (mongoc_socket_t *sock,
                              void *buf,
                              size_t buflen,
                              int flags,
                              int64_t expire_at);

       • buflen: A size_t with the number of bytes to receive.

       • flags: flags for recv().

       • expire_at:  A  int64_t with the time to expire in monotonic time using System Clock <https://www.mongoc
         .org/libbson/current/bson_get_monotonic_time.html>, which is in microseconds.
