https://svn.boost.org/trac10/ticket/8680 <p> The documentation for <a href="http://www.boost.org/doc/libs/1_53_0/libs/iostreams/doc/tutorial/container_device.html">Boost.iosteams:Tutorial:Container_Device</a> refers to seekable_device as existing in <a href="http://www.boost.org/doc/libs/1_53_0/boost/iostreams/concepts.hpp">boost/iostreams/concepts.hpp</a>. However it does not exist. Either the documentation should be update or something along the lines of the following should be added to concepts.hpp.<br /> </p> <pre class="wiki">typedef device&lt;seekable&gt; seekable_device; typedef wdevice&lt;seekable&gt; wseekable_device; </pre><p> Not sure if that should be wseekable_device or seekable_wdevice. The latter seems to better match the filter typedef's. </p> <p> Alternatively the documentation could be updated to refer to device[seekable]. </p> en-us /htdocs/site/boost.png https://svn.boost.org/trac10/ticket/8680 Trac 1.4.3 stefan.cloudt@… Wed, 08 Nov 2017 12:34:57 GMT
