title: Global named event equivalent in Unix
body: <p>What is the global named event object equivalent in Unix? I need to create a named event-like object in unix so that another process can set it</p>
  
  <p>pseudocode in Win32:</p>
  
  <pre><code>HANDLE hEvent=CreateEvent(...,"Global\\CSAPP");
  while(1)
  {
      WaitForSingleObject(hEvent);
      ...
  }
  </code></pre>
  
  <p>In another process:</p>
  
  <pre><code>HANDLE hEvent=OpenEvent(...,"Global\\CSAPP");
  SetEvent(hEvent);
  </code></pre>
