It would also be possible, I think, to make an adapter that actually creates a shared mutex from a normal one. I've never had to write a read/write mutex but I guess that this is how they are implemented internally.
It's a bit more complicated than that. boost::shared_mutex is implemented on top of boost::mutex and boost::condition_variable for pthreads: take a look.
Hmm, so it looks like it would be straightforward to convert the pthread implementation of shared_mutex into an adapter that can convert an arbitrary mutex type (conforming to the boost.thread Lockable concept) into a shared mutex, by turning its boost::mutex into a template type? -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.6 (GNU/Linux) iD8DBQFIQATi5vihyNWuA4URAtDSAJ44PVA1aGFm8m8StlSXukwUi3nw2gCfQnkm p0RpVNNKfpnvaA0EHT1CDj0= =DFq3 -----END PGP SIGNATURE-----
