.. saslman:: sasl_encodev(3)
.. _sasl-reference-manpages-library-sasl_encodev:
==================================================================
**sasl_encodev** - Encode data for transport to authenticated host
==================================================================
Synopsis
========
.. code-block:: C
#include <sasl/sasl.h>
int sasl_encode(sasl_conn_t *conn,
const char * input,
unsigned inputlen,
const char ** output,
unsigned * outputlen);
int sasl_encodev(sasl_conn_t *conn,
const struct iovec * invec,
unsigned numiov,
const char ** output,
unsigned * outputlen);
Description
===========
**sasl_encode** encodes data to be sent to be sent to a remote host who we’ve
had a successful authentication session with. If there is a negotiated
security the data in signed/encrypted and the output should be sent
without modification to the remote host. If there is no security layer the
output is identical to the input.
**sasl_encodev** does the same, but for a `struct iovec` instead
of a character buffer.
.. c:function:: int sasl_encode(sasl_conn_t *conn,
const char * input,
unsigned inputlen,
const char ** output,
unsigned * outputlen);
:param conn: is the SASL connection context
:param output: contains the decoded data and is allocated/freed by
the library.
:param outputlen: length of `output`.
.. c:function:: int sasl_encodev(sasl_conn_t *conn,
const struct iovec * invec,
unsigned numiov,
const char ** output,
unsigned * outputlen);
:param conn: is the SASL connection context
:param output: contains the decoded data and is allocated/freed by
the library.
:param outputlen: length of `output`.
Return Value
============
SASL callback functions should return SASL return codes.
See sasl.h for a complete list. :c:macro:`SASL_OK` indicates success.
Other return codes indicate errors and should be handled.
