DisableThreadLibraryCalls函式簡介
1、函式原型
BOOL WINAPI DisableThreadLibraryCalls(
__inHMODULE hModule
);
功能：
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式的工作集大小。
參數：
HMODULE hModule，將要被禁用DLL_THREAD_ATTACH和DLL_THREAD_DETACH通知的dll的模組句柄。
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運行時庫進行連結(CRT，C run-time library ).時，不要使用該函式，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）LibraryUse Kernel32.lib.
4）DLLRequires Kernel32.dll.

簡介
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式的工作集大小。
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的模組句柄。
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.
注意事項
