intsasl_getopt_t(void*context,constchar*plugin_name,constchar*option,constchar**result,unsigned*len);sasl_getopt_t  is  used  to retrieve an option, often mechanism specific, from the application. An
              example of this is requesting what KERBEROS_V4 srvtab file to use.

              Parameters

                     • context – is the SASL connection context

                     • plugin_name – is the plugin this value is for.

                     • option –  is  a  string  representing  the  option.  A  common  option  that  all  server
                       applications  should  handle  is  the method for checking plaintext passwords.  See the ‐
                       administratorsguide for a full description of this option.

              Memory management of options supplied by the getopt callback should be done  by  the  application,
              however,  any  requested option must remain available until the callback is no longer valid.  That
              is, when sasl_dispose(3) is called for a the connection it is associated with,   or   sasl_done(3)
              is called for global callbacks.

       SASL  callback  functions  should  return  SASL  return  codes.   See sasl.h for a complete list. SASL_OK
       indicates success.

       Other return codes indicate errors and should be handled.
