Logging On and Off: CMC Sample

The following code example demonstrates how you can log on and off and use cmc_query_configuration to get system information.

/* Local variables used */

CMC_return_code Status;
CMC_boolean     UI_available;   /* True if an interface is allowed */
CMC_session_id  Session;

/* Find out if user interface (UI) is available with this 
   implementation before starting.*/

Status = cmc_query_configuration(
              0,                      /* No session handle         */
              CMC_CONFIG_UI_AVAIL,    /* See if UI is available.   */
              (void *)&UI_available,  /* Return value              */
              NULL);                  /* No extensions             */
    /* Error handling */

/* Log onto system using UI. */

Status = cmc_logon(
              NULL,                   /* Default service           */
              NULL,                   /* Prompt for user name      */
              NULL,                   /* Prompt for password       */
              NULL,                   /* Default character set     */
              0,                      /* Default UI ID             */
              CMC_VERSION,            /* Version 1 CMC calls       */
              CMC_LOGON_UI_ALLOWED |  /* Full logon UI             */
              CMC_ERROR_UI_ALLOWED,   /* Use UI to display errors. */
              &Session,               /* Returned session ID       */
              NULL);                  /* No extensions             */
    /* Error handling */

/* Do various CMC calls. */

/* Log off from the implementation. */

Status = cmc_logoff(
              Session,            /* Session ID                    */
              0,                  /* No UI will be used.           */
              0,                  /* No flags                      */
              NULL);              /* No extensions                 */
    /* Error handling */
