System V to POSIX Semaphore Wrapper

[pikpik]

Hi,

As part of porting a (mostly C++) library[1] to a "new" operating system[2], I'm trying to link the library's semaphore class to the platform's semaphore implementation. The problem is that the library assumes that the semaphore implementation will be a modern POSIX one[3] but the operating system's semaphores are modeled after System V[4].

My question is primarily if anyone knows of a wrapper of C (or C++) code that will act as an emulation layer around the System V semaphores in a way that will present "modern" POSIX semaphores to the library I'm porting. A caveat is that any used code must be compatible with the BSD license.

Thank you,
pikpik
