注意，需要的接口版本必須是1.9.0.17:

#include <stdio.h>
#include <stdlib.h>
#include <string.h>

#include "npupp.h"

NPNetscapeFuncs NPNFuncs;


char *
NP_GetMIMEDescription()
{
  return (char*)"application/mozill-plugin6:.foo5:Scriptability Plugin5";
}

NPError
NP_GetValue(void* future, NPPVariable variable, void *value)
{
  //return NPP_GetValue((NPP_t *)future, variable, value);

  NPP instance = (NPP_t *)future;

  if(instance == NULL)
    return NPERR_INVALID_INSTANCE_ERROR;

  switch (variable) {
  case NPPVpluginNameString:
    *((char **)value) = (char*)"NPRuntimeTest";
    break;

  case NPPVpluginDescriptionString:
    *((char **)value) = (char*)"NPRuntime scriptability API test plugin";
    break;

  case NPPVpluginScriptableNPObject:
    //*(NPObject **)value = plugin->GetScriptableObject();
    break;

  default:
    return NPERR_GENERIC_ERROR;
  }

  return NPERR_NO_ERROR;
}
