如何檢查dll的引用計數？如何知道dll的加載位置？

如您所知，如果LoadLibrary的調用指定了一個DLL模塊已經映射到調用進程的地址空間中，該函數只是返回DLL的句柄並遞增模塊的引用計數。如何檢查dll的引用計數？如何知道dll的加載位置？

某處，我需要得到一個DLL的引用計數。如何獲得dll的引用計數？如何知道dll的加載位置？謝謝。

有趣的問題，但爲什麼你要去做這個？我敢打賭，有一種更簡單的方法可以實現你的目標。 – 2010-08-24 03:22:18

我想通過調用FreeLibrary來卸載dll，但它仍然被加載。我猜在某處引用它，所以我想檢查參考計數調試。 – ldlchina 2010-08-24 03:32:04

爲此，請使用Dependency Walker。它比一些插入的代碼更強大。 – MSalters 2010-08-24 06:42:23

該信息不適用於通過公共API afaik。你的場景是什麼？運行AppVerifier將捕獲您使用模塊（或任何其他）手柄所犯的任何錯誤。

我把它搜索了一下，發現這個article聲稱提供了答案。 抱歉，我不能提供更多的幫助：

+1對於你的觀點，以編程方式獲得計數 – Chubsdad 2010-08-24 03:22:01

@C Johnson，你試過了嗎？此解決方案取決於未記錄的功能，這些功能無法在未來版本的Windows中使用。 – 2010-08-24 04:27:33

實際上，它們甚至不能保證能在Windows的當前版本中工作:-) – paxdiablo 2010-08-24 04:58:07

如果它是一個非編程的方式（感謝C.Johnson給了這一觀點），WinDBG的可幫助

看的dll！它是變種。 ！

DLL - 負載 計數

編輯所有加載的模塊2：

如果你想從所有正在從進程中加載​​的DLL哪裏知道，有兩種方法：

a。看命令

「BU KERNEL32 LoadLibraryExW！」;如/畝 $ {/ V：MyAlias} POI（@ ESP + 4）; .if（ $ spat（\「$ {MyAlias} \」，\「MYDLL \」） ！= 0）{kn; }的.else {G}」，「

在上述URL

b

。在WinDBG下運行該進程。 Debug-> Even Filter並選擇「Load Module」並將其設置爲「Execution」下的「Enabled」。在「繼續」下將其設置爲「未處理」。

其中一個應該可以幫助你。

@ jack2000：如果它是用於調試的目的，正如您在其他地方提到的那樣，WinDBG和它的每一個不斷增加的強大功能應該肯定會讓你頭痛不已。 – Chubsdad 2010-08-24 04:05:28

@ jack2000：檢查編輯2下的信息是否有幫助 – Chubsdad 2010-08-24 06:43:19

我不確定您完全瞭解LoadLibrary/FreeLibrary是如何工作的。當你完成它時，你可以調用FreeLibrary，並減少加載時增加的引用計數。如果您的流程的其他部分仍在使用它，那可能不是您的擔心。

引用計數可能會告訴你它已被「加載」了多少次，但無助於弄清楚是誰加載了它。

進程管理器可以告訴誰正在使用給定的DLL。 – Chubsdad 2010-08-24 03:54:24

+0

@chubsdad，它會告訴你哪個進程正在使用它，但它會告訴你它是從一個進程中加載​​的。我的理解是，這一切都發生在一個單獨的過程中：'FreeLibrary'是一個進程內事物，引用計數不跨越進程邊界，它們僅用於映射到本地地址空間。 – paxdiablo 2010-08-24 04:17:47

當然，最好知道它在哪裏加載。:) – ldlchina 2010-08-24 05:12:15

您可以在Module32First()/Module32Next()的進程中枚舉加載的模塊，然後使用MODULEENTRY32.GlblcntUsage來檢查它的引用計數。我不確定這是多麼可靠。

這是一種「祕密」的方式來獲取有關任何進程的加載DLL的信息。它可以在Windows 10上運行。請注意，ustring是我個人特殊的字符串實現，可以相應地進行替換。 值得注意的是peb_ldr_data.InMemoryOrderModuleList.Flink。它的鏈接列表與所有加載的DLL。它在MSDN文檔中說，當到達最後一個條目時它將指向它自己。事實並非如此。它很好地恢復到列表中的第一個條目。至少在Win10 Pro中。 LDR_MODULE :: LoadCount是你正在尋找我相信。

MVH 馬蒂亞斯

嗯上升技保持...它可能無法正常在Win10工作...生病回來。

3件事情是相關的。它在Win 10中可以工作，但LoadCount不顯示參考計數。只有其動態（6）或靜態（-1）

PEB_LDR_DATA：有不同的結構浮動。該系統中的一個：

typedef struct _PEB_LDR_DATA { 
    BYTE Reserved1[8]; 
    PVOID Reserved2[3]; 
    LIST_ENTRY InMemoryOrderModuleList; 
} PEB_LDR_DATA, *PPEB_LDR_DATA;

而在一些用戶的例子用戶定義：

typedef struct _PEB_LDR_DATA2 
    { 
     ULONG Length; 
     UCHAR Initialized; 
     PVOID SsHandle; 
     LIST_ENTRY InLoadOrderModuleList; 
     LIST_ENTRY InMemoryOrderModuleList; 
     LIST_ENTRY InInitializationOrderModuleList; 
     PVOID EntryInProgress; 

    } PEB_LDR_DATA2, *PPEB_LDR_DATA2;

這開始變得一團糟。他們都似乎工作，但懷疑。內存在某種程度上被抵消了。儘管如此，您可以通過這種方式獲得有關進程（任意Exe程序）加載的模塊的信息，但LoadCount在Windows中不顯示實際的引用計數> 7.

Btw我再次檢查使用USER定義的PEB_LDR_DATA結構。該系統會產生不準確。 LDR_MODULE中的一些成員變成垃圾。爲什麼？我不知道。 （「Det fixarbåtklubben...」）。

要壞...

使用率注入.dll文件的：

// Someone reserved us, let's force us to shutdown. 
while(GetModuleLoadCount(dll) > 1) 
    FreeLibrary(dll); 

FreeLibraryAndExitThread(dll, 0);
