I hope this helps . First, you create a Semaphore with 10 initial permits, as explained here. It is not an upper limit, so release() can make the number of available permits go above 10.
Also, look at the code below:
synchronized (this.lock) {
    s.acquire(); // consume resource
synchronized (this.lock) {
    s.release(); // produce an resource

After applying semaphore, the code still doesn't work as expected

should help you out The clang error is because ThreadAdd is declared as void * and doesn't return anything. Just return 0.
One issue is that sem_wait and sem_post can fail. In that case, they return -1 and you need to check errno for the cause. Your code looked okay to me so I tried it on two machines: - SE Linux, worked just fine - Mac, sem_wait failed.

will be helpful for those in need Your locking is too coarse. As a general pattern, unless you have very exceptional circumstances, all locking should be of the form:
try {
} finally {
public void enter(){
    try {
        isOccupied = true;
    } catch (InterruptedException e) {
    } finally {

public void leave(){
    try {
        isOccupied = false;
    } catch (InterruptedException e) {
    } finally {

Turning off monitor with JNA in Java doesn't work as expected

hop of those help? It's possible that "doesn't work as expected" means your expectations are wrong.
Of note, there are some problems with the linked code, which I assume you used verbatim. The SendMessage function is mapped twice. The first mapping is correct, but never used:
  LRESULT SendMessageA(HWND paramHWND, int paramInt, WPARAM paramWPARAM,
        LPARAM paramLPARAM);
  LRESULT SendMessageA(HWND paramHWND, int paramInt, int paramInt2,
        LPARAM paramLPARAM);
