Avisynth 2,5/2,6 Plugin

[Garfield]

Code:

AVSValue LoadPlugin(AVSValue args, void* user_data, IScriptEnvironment* env){
  extern const AVS_Linkage* const AVS_linkage; // In interface.cpp
  bool quiet = (user_data != 0);
  args = args[0];
  const char* result=0;
  for (int i=0; i<args.ArraySize(); ++i) {
    HMODULE plugin;
    const char* plugin_name = args[i].AsString();
    if (MyLoadLibrary(plugin_name, &plugin, quiet, env)) {
      typedef const char* (__stdcall *AvisynthPluginInit3Func)(IScriptEnvironment* env, const AVS_Linkage* const vectors);
      AvisynthPluginInit3Func AvisynthPluginInit3 = (AvisynthPluginInit3Func)GetProcAddress(plugin, "AvisynthPluginInit3");
      if (!AvisynthPluginInit3) {
        AvisynthPluginInit3 = (AvisynthPluginInit3Func)GetProcAddress(plugin, "_AvisynthPluginInit3@8");
        if (!AvisynthPluginInit3) {  // Try for 2.5 version
          typedef const char* (__stdcall *AvisynthPluginInit2Func)(IScriptEnvironment* env);
          AvisynthPluginInit2Func AvisynthPluginInit2 = (AvisynthPluginInit2Func)GetProcAddress(plugin, "AvisynthPluginInit2");
          if (!AvisynthPluginInit2) {
            AvisynthPluginInit2 = (AvisynthPluginInit2Func)GetProcAddress(plugin, "_AvisynthPluginInit2@4");
            if (!AvisynthPluginInit2) {  // Older version
              FreeLibrary(plugin);
              if (quiet) {
                // remove the last handle from the list
                HMODULE* loaded_plugins = (HMODULE*)env->GetVar("$Plugins$").AsString();
                int j=0;
                while (loaded_plugins[j+1]) j++;
                loaded_plugins[j] = 0;
              } else {
                env->ThrowError("Plugin %s is not an AviSynth 2.6 or 2.5 plugin.",plugin_name);
              }
            } else {
              result = AvisynthPluginInit2(env);
            }
          } else {
            result = AvisynthPluginInit2(env);
          }
        } else {
          result = AvisynthPluginInit3(env, AVS_linkage);
        }
      } else {
        result = AvisynthPluginInit3(env, AVS_linkage);
      }
    }
  }
  if (loadplugin_prefix) free((void*)loadplugin_prefix);  // Tritical May 2005
  loadplugin_prefix = 0;
  return result ? AVSValue(env->SaveString(result)) : AVSValue();
}

Das ist das einzige was ich zu den verschiedenen Versionen von AvisynthPluginInit gefunden habe.
