Hi,
I search "spinlock" @boost.org, which turned up nothing. Anyone aware of such an implementation.
Yes I am aware of an implementation. I have implemented a Spin Lock in boost style that I have not yet submitted, even to the vault. It is tested on Windows, but it should work on all platforms that support interlocked arithmetic operations. If there is interest I could submit this early version to the vault.
Thanks in advance. Greg

A while ago I presented some benchmarks comparing different types of mutex including a spinlock. See e.g. http://thread.gmane.org/gmane.comp.lib.boost.devel/166875. My implementations at that time were just ad-hoc code for benchmarking. I've recently been turning it into something more useful and will post a message here about it soon. To make this cross-platform, we really need an implementation of atomics like e.g. N2427. Phil.

Your implementation posted on gmane.org is straightforward and efficient! How does it compare with your latest version? To make this cross-platform, we really need an implementation of
atomics like e.g. N2427.
Your impl. is Linux-based, while Neil's is Windows exclusive. Perhaps you could cooperate with Neil and come up with a joint contribution? Greg
