.SH DESCRIPTION

.B sasl_decode
decodes data received. After succesful 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.

.I output
is allocated by the library and must be freed by the application. One should not to give sasl_decode more data than the negotiated maxbufsize (see sasl_getprop).

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.

.PP
