PDF-[FREE]-C++ Concurrency in Action

The Desired Brand Effect Stand Out in a Saturated Market with a Timeless Brand. This motivated an ongoing shared effort by the standards committees to specify concurrent behaviour in the next versions of both languages They aim to provide strong guarantees for racefree programs together with new but subtle relaxedmemory atomic Slide . 1.
