  67 <p>In order to identify a system-wide object such as a shared memory segment or a named synchronization primitive the object has to be given a name. The format of the name is specific to the operating system and the <code class="computeroutput"><a class="link" href="object_name.html" title="Class object_name">object_name</a></code> class provides an abstraction for names of objects. It also provides means for scoping, which allows to avoid name clashes between different processes.</p>
  68 <p>The object name is a UTF-8 encoded string. The portable object name should consist of the following characters:</p>
  69 <pre class="programlisting">

  82 Use of other characters may result in non-portable system-specific behavior.</p>
  83 <p>The name can have one of the following scopes:</p>
  84 <div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; ">
  85 <li class="listitem"><p><code class="computeroutput">global</code> - objects within this scope are visible to any process on the system. In order to use this scope the process may need to have extended privileges. This scope is not available for Windows Store applications. </p></li>
  86 <li class="listitem"><p><code class="computeroutput">user</code> - objects within this scope can be opened by processes running under the same user as the current process. </p></li>
  87 <li class="listitem"><p><code class="computeroutput">session</code> - objects within this scope are visible to processes within the session of the current process. The definition of a session may vary between operating systems. On POSIX, a session is typically a group of processes attached to a single virtual terminal device. On Windows a session is started when a user logs into the system. There is also a separate session for Windows services. </p></li>
  88 <li class="listitem"><p><code class="computeroutput">process_group</code> - objects within this scope are visible to processes within the process group of the current process. Currently, on Windows all processes running in the current session are considered members of the same process group. This may change in future.</p></li>
  89 </ul></div>
  90 <p>
  91 The scopes are not overlapping. For instance, if an object is created in the global scope, the object cannot be opened with the same name but in user's scope.</p>
  92 <p>Note that name scoping is not a security feature. On some systems any process on the system has technical capability to open objects within any scope. The scope is only used to help avoid name clashes between processes using <code class="computeroutput"><a class="link" href="object_name.html" title="Class object_name">object_name</a></code> to identify objects. </p>
