NAME

       sasl_decode - Cyrus SASL documentation

SYNOPSIS

       #include <sasl/sasl.h>

       int sasl_decode(sasl_conn_t *conn,
                      const char * input,
                       unsigned inputlen,
                      const char ** output,
                      unsigned * outputlen);

DESCRIPTION

       int sasl_decode(sasl_conn_t *conn,

       const char * input,

       unsigned inputlen,

       const char ** output,

       unsigned * outputlen);
              sasl_decode  decodes    data   received.   After   successful  authentication  this
              function should be called on all   data  received.   It   decodes   the  data  from
              encrypted  or  signed form to plain data. If there was no security layer negotiated
              the output is identical to the input.

              Parameters

                     • conn – is the SASL connection context

                     • output – contains the decoded data and is allocated/freed by the library.

                     • outputlen – length of output.

              One should not give  sasl_decode  more  data  than  the negotiated maxbufsize  (see
              sasl_getprop(3)).

              Note   that   sasl_decode   can   succeed and outputlen can be zero. If this is the
              case simply wait for  more  data  and call sasl_decode again.

RETURN VALUE

       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.
