WPP synchronization in x265

[RARY]

How does synchronization happen when Wavefront parallel processing(WPP) is enabled and what's the exact mechanism in x265 and specifically in the processRowEncoder function which handles encoding part of each row in a frame as wavefronts?

Also,(if you can help)what are the functions and flags involved in it??
