We can catch it if it's included before something from vamp-hostsdk. If it's included after something from vamp-hostsdk, it will work OK anyway. The remaining problem case is where nothing from vamp-hostsdk is included in the same file. We can't catch that. </p> + +<p>Definition at line <a class="el" href="plugguard_8h_source.html#l00072">72</a> of file <a class="el" href="plugguard_8h_source.html">plugguard.h</a>.</p> + +</div> +</div> +<a class="anchor" id="a1a2724ea453971288d3218e4eab3072c"></a><!-- doxytag: member="plugguard.h::_VAMP_SDK_PLUGSPACE_BEGIN" ref="a1a2724ea453971288d3218e4eab3072c" args="(h)" --> +<div class="memitem"> +<div class="memproto"> + <table class="memname"> + <tr> + <td class="memname">#define _VAMP_SDK_PLUGSPACE_BEGIN</td> + <td>(</td> + <td class="paramtype"> </td> + <td class="paramname">h</td><td>)</td> + <td></td> + </tr> + </table> +</div> +<div class="memdoc"> + +<p>Definition at line <a class="el" href="plugguard_8h_source.html#l00075">75</a> of file <a class="el" href="plugguard_8h_source.html">plugguard.h</a>.</p> + +</div> +</div> +<a class="anchor" id="ac879bb1077ecc6132ea3581ef9033753"></a><!-- doxytag: member="plugguard.h::_VAMP_SDK_PLUGSPACE_END" ref="ac879bb1077ecc6132ea3581ef9033753" args="(h)" --> +<div class="memitem"> +<div class="memproto"> + <table class="memname"> + <tr> + <td class="memname">#define _VAMP_SDK_PLUGSPACE_END</td> + <td>(</td> + <td class="paramtype"> </td> + <td class="paramname">h</td><td>)</td> + <td></td> + </tr> + </table> +</div> +<div class="memdoc"> + +<p>Definition at line <a class="el" href="plugguard_8h_source.html#l00076">76</a> of file <a class="el" href="plugguard_8h_source.html">plugguard.h</a>.</p> + +</div> +</div> +</div> +</div> + <div id="nav-path" class="navpath"> + <ul> + <li class="navelem"><a class="el" href="plugguard_8h.html">plugguard.h</a> </li> + + <li class="footer">Generated on Tue Oct 4 2011 14:38:49 for VampPluginSDK by + <a href="http://www.doxygen.org/index.html"> + <img class="footer" src="doxygen.png" alt="doxygen"/></a> 1.7.5.1 </li> + </ul> + </div> + + +</body> +</html>
