DisableThreadLibraryCalls

鎖定

DisableThreadLibraryCalls，計算機函數。實現禁用指定的DLL的DLL_THREAD_ATTACH和DLL_THREAD_DETACH通知，減小某些程序的工作集大小。

中文名: DisableThreadLibraryCalls
返回值: 成功返回非零值

參數: HMODULE hModule
功能: 減小某些程序的工作集大小

DisableThreadLibraryCalls簡介

1、函數原型

BOOL WINAPI DisableThreadLibraryCalls(

__in HMODULE hModule

);

參數：

HMODULE hModule，將要被禁用DLL_THREAD_ATTACH和DLL_THREAD_DETACH通知的dll的模塊句柄。

返回值：

成功返回非零值；失敗則返回零值。

注意事項：

1）當dll使用靜態C運行時庫進行鏈接(CRT，C run-time library ).時，不要使用該函數，因為此時dll需要DLL_THREAD_ATTACH 和DLL_THREAD_DETATCH通知才能發揮正常作用。

2）Header Declared in Winbase.h; include Windows.h.

3）Library Use Kernel32.lib.

4）DLL Requires Kernel32.dll.

This function disables the DLL_THREAD_ATTACH and DLL_THREAD_DETACH notifications for the DLL specified by the hLibModule parameter.

Using this function can reduce the size of the working code set for some applications.

禁用指定的DLL的DLL_THREAD_ATTACH和DLL_THREAD_DETACH通知，這樣可以減小某些程序的工作集大小。

BOOL DisableThreadLibraryCalls(

HMODULE hLibModule

);

Parameters：參數：

hLibModule

[in] Handle to the DLL module for which the DLL_THREAD_ATTACH and DLL_THREAD_DETACH notifications are to be disabled.

將要被禁用DLL_THREAD_ATTACH和DLL_THREAD_DETACH通知的dll的模塊句柄。

Return Values：返回值：

Nonzero indicates success. 成功返回非零值；

Zero indicates failure.失敗則返回零值。

To get extended error information, call GetLastError.

Remarks：

Windows CE does not support static-thread local storage; therefore, the only restriction for specifying a DLL to disable is that it is a valid module.

The DisableThreadLibraryCalls function lets a DLL disable the DLL_THREAD_ATTACH and DLL_THREAD_DETACH notification calls.

This can be a useful optimization for multithreaded applications that have many DLLs, frequently create and delete threads, and whose DLLs do not need these thread-level

notifications of attachment/detachment.

By disabling the notifications, the DLL initialization code is not paged-in because a thread is created or deleted, which reduces the size of the application's working code set.

Disabling the notification calls can be used for any DLL where there is no thread-level tracking required. If you need to track resources on a thread-by-thread basis, the notification

should not be turned off.

To implement the optimization, modify a DLL's DLL_PROCESS_ATTACH code to call DisableThreadLibraryCalls.

Drivers that exist in the Device Manager Device.exe process space should call DisableThreadLibraryCalls if no thread-specific data is needed.

Requirements：

OS Versions: Windows CE 3.0 and later.

Header: Winbase.h.

Link Library: Coredll.lib.
