我正在尝试实现一个 webkit 插件。我知道 webkit 插件采用 NPAPI，所以我从 mozilla 网站上查找，发现它很有帮助（对于 moziila，它是 Gecko 插件，但也采用 NPAPI）。好吧，还是有一些问题，例如，当我编写 NPP_Destroy 方法时，我需要调用 NPNetscapeFuncs 的释放对象。我从android源代码中检查了NPNetscapeFuncs的定义，releaseobject的定义是这样的：
typedef struct _NPNetscapeFuncs {
uint16_t size;
uint16_t version;
NPN_GetURLProcPtr geturl;
NPN_PostURLProcPtr posturl;
NPN_RequestReadProcPtr requestread;
NPN_NewStreamProcPtr newstream;
NPN_WriteProcPtr write;
NPN_DestroyStreamProcPtr destroystream;
NPN_StatusProcPtr status;
NPN_UserAgentProcPtr uagent;
NPN_MemAllocProcPtr memalloc;
NPN_MemFreeProcPtr memfree;
NPN_MemFlushProcPtr memflush;
NPN_ReloadPluginsProcPtr reloadplugins;
NPN_GetJavaEnvProcPtr getJavaEnv;
NPN_GetJavaPeerProcPtr getJavaPeer;
NPN_GetURLNotifyProcPtr geturlnotify;
NPN_PostURLNotifyProcPtr posturlnotify;
NPN_GetValueProcPtr getvalue;
NPN_SetValueProcPtr setvalue;
NPN_InvalidateRectProcPtr invalidaterect;
NPN_InvalidateRegionProcPtr invalidateregion;
NPN_ForceRedrawProcPtr forceredraw;
NPN_GetStringIdentifierProcPtr getstringidentifier;
NPN_GetStringIdentifiersProcPtr getstringidentifiers;
NPN_GetIntIdentifierProcPtr getintidentifier;
NPN_IdentifierIsStringProcPtr identifierisstring;
NPN_UTF8FromIdentifierProcPtr utf8fromidentifier;
NPN_IntFromIdentifierProcPtr intfromidentifier;
NPN_CreateObjectProcPtr createobject;
NPN_RetainObjectProcPtr retainobject;
NPN_ReleaseObjectProcPtr releaseobject;
NPN_InvokeProcPtr invoke;
NPN_InvokeDefaultProcPtr invokeDefault;
NPN_EvaluateProcPtr evaluate;
NPN_GetPropertyProcPtr getproperty;
NPN_SetPropertyProcPtr setproperty;
NPN_RemovePropertyProcPtr removeproperty;
NPN_HasPropertyProcPtr hasproperty;
NPN_HasMethodProcPtr hasmethod;
NPN_ReleaseVariantValueProcPtr releasevariantvalue;
NPN_SetExceptionProcPtr setexception;
NPN_PushPopupsEnabledStateProcPtr pushpopupsenabledstate;
NPN_PopPopupsEnabledStateProcPtr poppopupsenabledstate;
NPN_EnumerateProcPtr enumerate;
NPN_PluginThreadAsyncCallProcPtr pluginthreadasynccall;
NPN_ConstructProcPtr construct;
NPN_GetValueForURLProcPtr getvalueforurl;
NPN_SetValueForURLProcPtr setvalueforurl;
NPN_GetAuthenticationInfoProcPtr getauthenticationinfo;
NPN_ScheduleTimerProcPtr scheduletimer;
NPN_UnscheduleTimerProcPtr unscheduletimer;
NPN_PopUpContextMenuProcPtr popupcontextmenu;
NPN_ConvertPointProcPtr convertpoint;
} NPNetscapeFuncs;
但是 NPN_ReleaseObjectProcPtr（实际上是大多数功能）显然没有在 mozilla 中声明。所以我无法得到任何帮助。
我是否在 Mozilla 中向错误的地方求助？有人知道吗？提前致谢！
