First of all you have to initialise the gda library, i.e. to call the gda_init () function.

      gda_init ("TestGDA", "0.1", argc, argv);
    

After initialising you can work as usual or make a function with the whole stuff, calling gda_main_run(). Note that if you use this way you will need to call gda_main_quit() in order to finish the program.

void
do_stuff () {
	GdaClient *client;
	GdaConnection *connection;
      
	list_providers ();
	list_datasources ();
      
	client = gda_client_new ();
      
	g_print ("CONNECTING\n");
	connection = gda_client_open_connection (client, "calvaris", NULL, NULL,
						 GDA_CONNECTION_OPTIONS_READ_ONLY);

	g_print ("CONNECTED\n");
      
	execute_some_queries (connection);

	g_print ("ERRORS PROVED!\n");
      
	process_accounts (connection);
      
	g_object_unref (G_OBJECT (client));
}
      
      
int
main (int argc, char **argv)
{
	g_print ("STARTING\n");

	gda_init ("TestGDA", "0.1", argc, argv);
      	do_stuff();

	g_print("ENDING\n");      
}
