Boost C++ Libraries: Ticket #5448: Windows "\\\\?\\", "\\\\?\\UNC\\", and "\\\\.\\" path meta characters https://svn.boost.org/trac10/ticket/5448 <p> Windows treats "<br /><br />?<br />", "<br /><br />?<br />UNC<br />", and "<br /><br />.<br />" at the start of a path as meta characters signaling special handling of the remainder of the path. So, for example, "<br /><br />?<br />" should be treated as an empty path! </p> <p> See "Naming Files, Paths, and Namespaces", <a class="ext-link" href="http://msdn.microsoft.com/en-us/library/aa365247%28v=vs.85%29.aspx"><span class="icon">​</span>http://msdn.microsoft.com/en-us/library/aa365247%28v=vs.85%29.aspx</a> </p> <p> Ticket 5405 supplied a patch that allows class path to handle a portion of what this implies, but does not deal with the general problem. </p> <p> A few test cases have been added to path_test.cpp, but they are currently commented out. </p> en-us Boost C++ Libraries /htdocs/site/boost.png https://svn.boost.org/trac10/ticket/5448 Trac 1.4.3 Beman Dawes Sat, 09 Apr 2011 14:40:28 GMT <link>https://svn.boost.org/trac10/ticket/5448#comment:1 </link> <guid isPermaLink="false">https://svn.boost.org/trac10/ticket/5448#comment:1</guid> <description> <p> The <a class="wiki" href="https://svn.boost.org/trac10/wiki/WikiFormatting">WikiFormatting</a> messed up the meta characters.
