.. saslman:: sasl_server_step(3)
.. _sasl-reference-manpages-library-sasl_server_step:
=======================================================================
**sasl_server_step** - Perform a step in the authentication negotiation
=======================================================================
Synopsis
========
.. code-block:: C
#include <sasl/sasl.h>
int sasl_server_step(sasl_conn_t *conn,
const char *clientin,
unsigned clientinlen,
const char ** serverout,
unsigned * serveroutlen);
Description
===========
.. c:function:: int sasl_server_step(sasl_conn_t *conn,
const char *clientin,
unsigned clientinlen,
const char ** serverout,
unsigned * serveroutlen);
**sasl_server_step()** performs a step in the authentication negotiation. It
returns :c:macro:`SASL_OK` if the whole negotiation is successful and
:c:macro:`SASL_CONTINUE` if
this step is ok but at least one more step is needed.
:param conn: is the SASL connection context
:param clientin: is the data given by the client (decoded if the
protocol encodes requests sent over the wire)
:param clientinlen: is the length of `clientin`
:param serverout: set by the library and should be sent to the client.
:param serveroutlen: length of `serverout`.
Return Value
============
SASL callback functions should return SASL return codes.
See sasl.h for a complete list. :c:macro:`SASL_CONTINUE` indicates success
and that there are more steps needed in the authentication. :c:macro:`SASL_OK`
indicates that the authentication is complete.
Other return codes indicate errors and should either be handled or the authentication
session should be quit.
