Detailed Description

condition_variable is a C++ STL conditional variable (std::condition_variable) implementation using the instrumented MySQL conditional variable component API.

This allows for P_S instrumentation of conditional variables in components.

Note

Some methods are missing. Implement as needed.

Example usage:

#include <mysql/components/library_mysys/instrumented_condition_variable.h>
#include <mysql/components/library_mysys/instrumented_mutex.h>
namespace x {
  ...
  using mysql::condition_varible;
  ...
  condition_variable m(KEY_psi_cond);
  ...
  m.notifyAll(..);
  ...
};
