Programming Example of Working With Local sideinfo file 

RFC_OPTIONS         rfc_opt;       /* Parameter for RFC connection    */

RfcEnvironment(...);             /* Install error handling function */

rfc_opt.mode            = RFC_MODE_R3ONLY;   */     RFC to SAP system   */

rfc_opt.destination     = “BIN”;       /* Destination in local sideinfo   */

rfc_opt.connopt         = NULL;        /* Connect parameters in           */
                                       /* sideinfo file                   */

rfc_opt.client          = “000”;       /* Client in SAP system            */

rfc_opt.user            = “RFCTEST”;   /* CPIC or dialog user             */

rfc_opt.password        = “SECRET”;    /* Password                        */

rfc_opt.language        = “E”;         /* Logon language                  */

rfc_opt.trace           = 0;           /* No RFC trace                    */

rfc_handle = RfcOpen(&rfc_opt);     /* Open RFC connection             */

...

Local sideinfo file:

The local sideinfo file must be in the same directory as the RFC client program or must be defined with its path and file name by the environment variable SIDE_INFO.

Windows: set SIDE_INFO=d:\rfctest\sideinfo

The sideinfo entry for the above test could be as follows:

DEST=BIN
GWHOST=hs0311
GWSERV=sapgw53
PROTOCOL=I
LU=hs0311
TP=sapdp53
