SYNOPSIS

       #include <sasl/sasl.h>

       int sasl_client_new(const char *service,
                           const char *serverFQDN,
                           const char *iplocalport,
                           const char *ipremoteport,
                           const sasl_callback_t *prompt_supp,
                           unsigned flags,

DESCRIPTION

       int sasl_client_new(const char *service,

       const char *serverFQDN,

       const char *iplocalport,

       const char *ipremoteport,

       const sasl_callback_t *prompt_supp,

       unsigned flags,

       sasl_conn_t ** pconn);
              sasl_client_new()  creates  a  new  SASL context. This context will be used for all
              SASL   calls   for   one   connection.   It   handles   both   authentication   and
              integrity/encryption layers after authentication.

              Parameters

                     • service  –  the registered name of the service (usually the protocol name)
                       using SASL (e.g. “imap”).

                     • serverFQDN  –  the  fully  qualified  domain  name  of  the  server  (e.g.
                       “serverhost.example.com”).

                     • iplocalport  –  the  IP  and  port of the local side of the connection, or
                       NULL.  If iplocalport is NULL it will disable mechanisms that  require  IP
                       address  information.   This  string  must  be  in  one of the   following
                       formats:  “a.b.c.d;port”   (IPv4),   “e:f:g:h:i:j:k:l;port”   (IPv6),   or
                       “e:f:g:h:i:j:a.b.c.d;port” (IPv6)

                     • ipremoteport  –  the  IP and port of the remote side of the connection, or
                       NULL (see iplocalport)

                     • prompt_supp – a list of client interactions supported that  is  unique  to
                       this connection. If this parameter is NULL the global callbacks (specified
                       in sasl_client_init(3)) will  be  used.  See  sasl_callbacks(3)  for  more
                       information.

                     • flags – are connection flags (see below)

                     • pconn  –  the connection context allocated by the library.  This structure
                       will be used for all future SASL calls for this connection.

   Connection Flags
       Flags that may be passed to sasl_client_new():

       • SASL_SUCCESS_DATA: The protocol supports a server‐last send

       •

         SASL_NEED_PROXY: Force the use of a mechanism that supports an
                authorization id that is not the authentication id.

RETURN VALUE

       SASL callback functions should return SASL return codes.  See sasl.h for a complete  list.
       SASL_OK indicates success.

       The  following  return  codes  indicate  errors  and  should  either  be  handled  or  the
       authentication session should be quit:

       • SASL_NOMECH: No mechanism meets requested properties

       • SASL_BADPARAM: Error in config file

       • SASL_NOMEM: Not enough memory to complete operation
