Seqlocks

An implementation of sequence locks (seqlocks) for lock-free reads in C using atomics

• The header file contains the implementation.
• The source file contains usage examples of reading and writing

Note

The implementation assumes x86 architecture (i.e. the TSO memory model) where the memory ordering read --> acquire is enforced (and thus only requires a compiler barrier). For more information for a portable implementation, I recommend Boehms's [paper]{https://www.hpl.hp.com/techreports/2012/HPL-2012-68.pdf}
