    <title>Introduction to libatomic_ops</title>

    <para>
      <application>libatomic_ops</application> provides implementations for
      atomic memory update operations on a number of architectures. This allows
      direct use of these in reasonably portable code. Unlike earlier similar
      packages, this one explicitly considers memory barrier semantics, and
      allows the construction of code that involves minimum overhead across a
      variety of architectures.
