    mach_msg_type_number_t size= sizeof(info);

    kern_return_t kerr= task_info(mach_task_self(),

                                   TASK_BASIC_INFO,

                                  (task_info_t)&info,

                                  &size);

    if(kerr == KERN_SUCCESS ) 

    {

        return info.resident_size;

    }

    else

    {

       NSLog(@"Error withtask_info(): %s", mach_error_string(kerr));

    }

    return -1;

}
