Note In Boost. Control library auto-linking on Windows. In addition to these standard macros, Boost. Informally speaking, prevents all preceding memory operations to be reordered past this point. When defined, the library assumes the target CPU does not support mfence instruction used to implement thread fences. This static boolean constant indicates if any atomic object of this type is lock-free. The class implements the following operations:. Feature testing macros. Change bit number n in the variable to the opposite value, returning true if the bit was previously set to 1 and false otherwise. Subtract v from variable, returning true if the result is non-zero and false otherwise.

    This feature is not actually released yet: it appears to be in 'trunk' only. You can use a command line grep -R BOOST_ATOMIC_INT_LOCK_FREE boost/. 4 days ago std::atomic_int_least64_t, std::atomicint_least64_t>. defect reports were applied retroactively to previously published C++ standards.

    Enforce sequential consistency. When defined, all operations are implemented with locks. Similarly to integers, the following Boost.

    This is the case with very old CPUs pre-Pentium. If defined, the library assumes dynamic linking, otherwise static.

    Apply bit-wise "xor" with v to variable, returning true if the result is non-zero and false otherwise. When defined, support for floating point operations is disabled.

    In addition to these standard macros, Boost.

    Apply bit-wise "or" with v to variable, returning the result. Add v to variable, returning true if the result is non-zero and false otherwise. One widespread example of that is Intel x87 extended double format, which is typically stored as 80 bits of value padded with 16 or 48 unused bits.

    For example, you can build Boost.

    1. With GCC and compatible compilers this affects whether particular atomic operations are lock-free or not.

    2. Returns true if an exchange has been performed, and always writes the previous value back in expected.
