title: Compilation error : 'this' cannot be implicitly captured in this context
body: <p>I am trying to add a condition_variable to handle threads, but get a compilation error at this line:</p>
  
  <pre><code>this-&gt;cv.wait(lk, []{return this-&gt;ready;});
  </code></pre>
  
  <p>Looks like the for the variable this->ready, the 'this' is not in the right scope.</p>
  
  <p>In Java this can be handled with TestThread.this, is there anything in C++ doing the same?</p>
  
  <pre><code>void TestThread::Thread_Activity()
      {
          std::cout &lt;&lt; "Thread started \n";
          // Wait until ThreadA() sends data
          {
              std::unique_lock&lt;std::mutex&gt; lk(m);
              this-&gt;cv.wait(lk, []{return ready;});
          }
  
          std::cout &lt;&lt; "Thread is processing data\n";
          data += " after processing";
          // Send data back to ThreadA through the condition variable
          {
             // std::lock_guard&lt;std::mutex&gt; lk(m);
              processed = true;
             // std::cout &lt;&lt; "Thread B signals data processing completed\n";
          }
  
      }
  </code></pre>
