Is there any way to call system calls(like ioctl) in the SDK?

I need send a message a vmk device driver in the Java service, but I don't know whether current SDK support this.
In a local application, I can use system calls to open the device and call ioctl to operate it, as below:
    fd = open(dev, O_RDWR);
    ioctl(fd, IOCTL_GET_SOMETHING, some_info)
So now, I want to call the ioctl in the Java services through the SDK.
Is there any APIs in the SDK(like VI SDK) to run such system calls?

If there isn't, then what is the official method to send messages to a vmk device driver in the SDK?

Thanks a lot.
