sasl_client_step(3SASL) 		      Simple Authentication Security Layer Library Functions			   sasl_client_step(3SASL)

NAME

       sasl_client_step - acquire an auxiliary property context

SYNOPSIS

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

       int  sasl_client_step(sasl_conn_t *conn, const char *serverin, unsigned serverinlen, sasl_interact_t **prompt_need, const char **clientout,
       unsigned *clientoutlen);

DESCRIPTION

       Use the sasl_client_step() interface performs a step in the authentication negotiation. sasl_client_step() returns SASL_OK if the  complete
       negotiation  is successful. If the negotiation on step is completed successfuly, but at least one more step is required, sasl_client_step()
       returns SASL_CONTINUE. A client should not assume an authentication negotiaion is successful because the server	signaled  success  through
       the  protocol.  For  example, if the server signaled OK Authentication succeeded in IMAP, sasl_client_step() should be called one more time
       with a serverinlen of zero.

       If a call to sasl_client_step() returns SASL_INTERACT, the  library  requires  some  values  before  sasl_client_step()	can  proceed.  The
       prompt_need  structure  will  be  filled with the requests. The application should fulfull these requests and call sasl_client_step() again
       with identical parameters. The prompt_need parameter will be the same pointer as before, but it will have been filled in  by  the  applica-
       tion.

PARAMETERS

       conn		       The SASL connection context.

       serverin 	       The data given by the server. The data is decoded if the protocol encodes requests sent over the wire.

       serverinlen	       The length of the serverin.

       clientout	       clientout  and  clientoutlen are created. They contain the initial client response to send to the server. It is the
       clientoutlen	       job of the client to send them over the network to the server. Any protocol specific encodingthat is necessary, for
			       example base64 encoding, must be done by the client.

       prompt_need	       A list of prompts that are needed to continue, if necessary.

RETURN VALUES

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

ERRORS

       SASL_OK	       The call to sasl_client_start() was successful. Authentication is complete.

       SASL_CONTINUE   The call to sasl_client_start() was successful, but at least one more step is required for authentication.

       SASL_INTERACT   The library requires some values before sasl_client_step() can proceed.

       All  other  error  codes  indicate  an  error  situation  that  must  be  handled,  or  the  authentication  session  should  be  quit. See
       sasl_errors(3SASL) for information on SASL error codes.

NAME

       sasl_client_step - Perform a step in the authentication negotiation

SYNOPSIS

       #include <sasl/sasl.h>

       int sasl_client_step(sasl_conn_t *conn,
		      const char *serverin,
		      unsigned serverinlen,
		      sasl_interact_t ** prompt_need,
		      const char ** clientout,
		      unsigned * clientoutlen);

DESCRIPTION

       sasl_client_step()  performs  a	step  in  the  authentication  negotiation.  It returns SASL_OK if the whole negotiation is successful and
       SASL_CONTINUE if this step is ok but at least one more step is needed. A client should not assume an authentication negotiation is success-
       ful just because the server signaled success via protocol (i.e. if the server said ". OK Authentication succeeded" in IMAP sasl_client_step
       should still be called one more time with a serverinlen of zero.

       If SASL_INTERACT is returned the library needs some values to be filled in before it can proceed. The prompt_need structure will be  filled
       in with requests. The application should fulfill these requests and call sasl_client_start again with identical parameters (the prompt_need
       parameter will be the same pointer as before but filled in by the application).

       conn is the SASL connection context

       serverin is the data given by the server (decoded if the protocol encodes requests sent over the wire)

       serverinlen is the length of serverin

       clientout and clientoutlen is created. It is the initial client response to send to the server. It is the job of the client to send it over
       the network to the server.  Any protocol specific encoding (such as base64 encoding) necessary needs to be done by the client.

RETURN VALUE

       sasl_client_step  returns  an  integer  which corresponds to one of the following codes. SASL_CONTINUE indicates success and that there are
       more steps needed in the authentication. SASL_OK indicates that the authentication is complete. All other return codes indicate errors  and
       should either be handled or the authentication session should be quit.
