<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.
