SASL_DECODE(3SASL) Simple Authentication Security Layer Library Functions

NAME

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
The SASL connection context.


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

sasl_decode() returns an integer that corresponds to a SASL error
code.

ERRORS

SASL_OK
The call to sasl_decode() was successful.
