Detailed Description

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

This allows for P_S instrumentation of mutexes in components.

Example usage:

#include <mysql/components/library_mysys/instrumented_mutex.h>
namespace x {
  ...
  using mysql::mutex;
  ...
  mutex m(KEY_psi_mutex);
  ...
  std::unique_lock(m);
  ...
};
