  27 DESCRIPTION
  28 -----------
  29
  30
  31 libmemcached(3) allows you to plug in your own callbacks function used by
  32 libsasl to perform SASL authentication.
  33
  34 Please note that SASL requires the memcached binary protocol, and you have
  35 to specify the callbacks before you connect to the server.
  36
  37 :c:func:`memcached_set_sasl_auth_data()` is a helper function defining
  38 the basic functionality for you, but it will store the username and password
  39 in memory. If you choose to use this method you have to call
  40 :c:type:`memcached_destroy_sasl_auth_data` before calling
  41 :c:type:`memcached_free` to avoid a memory leak. You should NOT call
  42 :c:type:`memcached_destroy_sasl_auth_data` if you specify your own callback
  43 function with :c:func:`memcached_set_sasl_callbacks()`.
  44
  45 You as a client user have to initialize libsasl by using :c:type:`sasl_client_init` before enabling it in libmemcached, and you have to shut down libsasl by
  46 calling :c:func:`sasl_done()` when you are done using SASL from libmemcached.

  50 RETURN
  51 ------
  52
  53
  54 :c:func:`memcached_get_sasl_callbacks()` returns the callbacks currently used
  55 by this memcached handle. :c:func:`memcached_get_sasl_set_auth_data()` returns :c:type:`MEMCACHED_SUCCESS` upon success.
