Example: lrd_init

In the following example, lrd_init sets up the environment in the vuser_init section. Static variables InitInfo and DBTypeVersion are used as arguments.

#include "lrd.h"

/* This declaration should appear on your site exactly as it appears here. Do not change any of the fields of the structure. */

static LRD_INIT_INFO InitInfo = {LRD_INIT_INFO_EYECAT};

/* This declaration should be recorded at your site. Do not edit it. *

static LRD_DEFAULT_DB_VERSION DBTypeVersion[] =
{
    {LRD_DBTYPE_NONE, LRD_DBVERSION_NONE}
};

static void FAR *    OraEnv1;
static void FAR *    OraSvc1;
static void FAR *    OraSrv1;
static void FAR *    OraSes1;

{
    lrd_init(&InitInfo, DBTypeVersion);

        Oracle in object-relational mode*/

    lrd_initialize_db(LRD_DBTYPE_ORACLE, 2, 0);
    lrd_env_init(LRD_DBTYPE_ORACLE, &OraEnv1, 0, 0);

    // The second argument is the name of the server being used.

    lrd_server_attach(OraSrv1, "db_server_1", -1, 0, 0);
    lrd_ora8_attr_set_from_handle(OraSvc1, SERVER, OraSrv1, 0, 0);
