    How are atomics done in C99 (portably)?

    I'm trying to not use extensions, whenever possible.

    If it were that easy to do portably, the standards committee wouldn't have bothered with the whole atomics thing to begin with.
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.

    To be clear, I wasn't excluding libraries from my question. I'm fine with a library that performs arch-specific things, as long as it supports more than just x86.

    How about adding yet more clarity, by saying
    - what processors you care about (more than just x86 doesn't say anything)
    - what compilers you care about
    - what operating systems you care about
    - what range of atomics you care about
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
