cannam@21 50 Normal usage should be:.
cannam@21 51 <p>
cannam@21 52 <ul>
cannam@21 53 <li>Plugins include <a class="el" href="vamp-sdk_2Plugin_8h.html">vamp-sdk/Plugin.h</a> or <a class="el" href="vamp-sdk_2PluginBase_8h.html">vamp-sdk/PluginBase.h</a>. These files include this header, which specifies an appropriate namespace for the plugin classes to avoid any risk of conflict with non-plugin class implementations in the host on load.</li></ul>
cannam@21 54 <p>
cannam@21 55 <ul>
cannam@21 56 <li>Hosts include <a class="el" href="vamp-hostsdk_2Plugin_8h.html">vamp-hostsdk/Plugin.h</a>, <a class="el" href="vamp-hostsdk_2PluginBase_8h.html">vamp-hostsdk/PluginBase.h</a>, vamp-hostsdk/PluginHostAdapter, <a class="el" href="PluginLoader_8h.html">vamp-hostsdk/PluginLoader.h</a> etc. These files include <a class="el" href="hostguard_8h.html">vamp-hostsdk/hostguard.h</a>, which makes a note that we are in a host. A file such as <a class="el" href="vamp-hostsdk_2Plugin_8h.html">vamp-hostsdk/Plugin.h</a> then simply includes <a class="el" href="vamp-sdk_2Plugin_8h.html">vamp-sdk/Plugin.h</a>, and this guard header takes notice of the fact that it has been included from a host and leaves the plugin namespace unset.</li></ul>
cannam@21 57 <p>
cannam@21 58 Problems will occur when a host includes files directly from the vamp-sdk directory. There are two reasons this might happen: mistake, perhaps owing to ignorance of the fact that this isn't allowed (particularly since it was the normal mechanism in v1 of the SDK); and a wish to incorporate plugin code directly into the host rather than having to load it.<p>
cannam@21 59 What if the host does include a vamp-sdk header by mistake? 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.
