Detailed Description

MySQL condition variable implementation.

There are three "layers": 1) native_cond_*() Functions that map directly down to OS primitives. Windows - ConditionVariable Other OSes - pthread 2) my_cond_*() Functions that use SAFE_MUTEX (default for debug). Otherwise native_cond_*() is used. 3) mysql_cond*() Functions that include Performance Schema instrumentation. See include/mysql/psi/mysql_thread.h
