Detailed Description

A structure automatically aligned to cache line boundaries.

This structure is padded to occupy exactly one cache line (QB_LOCKFREE_CACHELINE_BYTES). It can be used as a base class or member to ensure that an object starts on a cache line boundary, which can help prevent false sharing in concurrent applications when different threads access adjacent data that might otherwise fall into the same cache line. Contains a raw array __raw__ for padding purposes.
