semaphore-compat provides a cross-platform implementation of system semaphores that abstracts over the unix and Win32 libraries.

It supports:

Creating (createSemaphore, freshSemaphore), opening (openSemaphore) and closing (destroySemaphore) semaphores.
Waiting on a semaphore:
- without blocking with tryWaitOnSemaphore,
- blocking forever, with waitOnSemaphore,
- blocking, in a separate thread and allowing interruption, with forkWaitOnSemaphoreInterruptible and interruptWaitOnSemaphore.
Releasing tokens to a semaphore (releaseSemaphore).
Querying the semaphore for its current value (getSemaphoreValue).
