sasl_decode

- decode data received

Synopsis

cc [ flag ... ] file ... -lsasl   [ library ... ]
#include <sasl/sasl.h>

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

Description

Use the sasl_decode() interface to decode data received. After authentication, call this function on all data received. The data is decoded from encrypted or signed form to plain data. If no security lay is negotiated, the output is identical to the input.

Do not give sasl_decode() more data than the negotiated maxbufsize. See sasl_getprop(3SASL).

sasl_decode() can complete successfully although the value of outputlen is zero. If this is the case, wait for more data and call sasl_decode() again.

Parameters

conn

input

Data received.

inputlen

The length of input

output

The decoded data. output must be allocated or freed by the library.

outputlen

The length of output.

Return Values
