If <a class="missing wiki">GetLastError</a>() was dirty before a call this code will fail even if GetModuleFileNameW() will success. Yes, on success, GetModuleFileNameW() doesn't reset last error to ERROR_SUCCESS. </p> en-us /htdocs/site/boost.png https://svn.boost.org/trac10/ticket/13455 Trac 1.4.3 Andrey Semashev Wed, 21 Feb 2018 14:49:17 GMT https://svn.boost.org/trac10/ticket/13455#comment:1 https://svn.boost.org/trac10/ticket/13455#comment:1 <ul> <li><strong>status</strong> <span class="trac-field-old">new</span> → <span class="trac-field-new">closed</span> </li> <li><strong>resolution</strong> → <span class="trac-field-new">invalid</span> </li> </ul> <p> Please, report this to Boost.DLL: <a class="ext-link" href="https://github.com/boostorg/dll/issues"><span class="icon">​</span>https://github.com/boostorg/dll/issues</a> </p> Ticket
