Detailed Description

A simple semaphore with increment and decrement functionality.

Its destruction will wait until the usage count is zero.

Synopsis:

// This will produce a deadlock
{
  asio::Semaphore semaphore;
  semaphore.increment();
 
} // The semaphore object's destructor waits until usage is zero again (decrement() call),
  // but it won't happen in this scenario.
 
 
{
  asio::Semaphore semaphore;
  semaphore.increment();
  semaphore.decrement();
} // Now the semaphore has usage count zero, it will be destroyed.
