Hi,

currently Synchro provides the same semaphore as Boost.Interprocess (counting semaphores), except that it uses Threads resources on a inter-threads context, and Interprocess resources on a inter-process context.

The library could provide binary semaphores (the difference is minimal). Could you talk us about your use case, and why a mutex cannot be used in your context?

Let me know if you need other kind of semaphores.

Best,
Vicente
