How to write a fast mutex?

I would like to have fast locks as Win32's InterlockedIncrement(). Currently I am using the swap assembler instruction. Is this correct or do I need to add a kind of memory barrier?

I would rather like to use the atomic_add function family but it doesn't seem to be available for user programs.

Does any have a suggestion in order to have fast locks?
