<p ><b>By using the native access functions you assert that you know what you're doing and how to fix problems caused by using them. If you don't, you shouldn't be using them.</b></p>
<p >Before the inclusion of <a class="el" href="glfw3native_8h.html">glfw3native.h</a>, you may define zero or more window system API macro and zero or more context creation API macros.</p>
<p >The chosen backends must match those the library was compiled for. Failure to do this will cause a link-time error.</p>
<p >The available window API macros are:</p><ul>
<li><code>GLFW_EXPOSE_NATIVE_WIN32</code></li>
<li><code>GLFW_EXPOSE_NATIVE_COCOA</code></li>
<li><code>GLFW_EXPOSE_NATIVE_X11</code></li>
<li><code>GLFW_EXPOSE_NATIVE_WAYLAND</code></li>
</ul>
<p >The available context API macros are:</p><ul>
<li><code>GLFW_EXPOSE_NATIVE_WGL</code></li>
<li><code>GLFW_EXPOSE_NATIVE_NSGL</code></li>
<li><code>GLFW_EXPOSE_NATIVE_GLX</code></li>
<li><code>GLFW_EXPOSE_NATIVE_EGL</code></li>
<li><code>GLFW_EXPOSE_NATIVE_OSMESA</code></li>
</ul>
<p >These macros select which of the native access functions that are declared and which platform-specific headers to include. It is then up your (by definition platform-specific) code to handle which of these should be defined.</p>
<p >If you do not want the platform-specific headers to be included, define <code>GLFW_NATIVE_INCLUDE_NONE</code> before including the <a class="el" href="glfw3native_8h.html">glfw3native.h</a> header.</p>
