看Wince驱动时，看到Init函数时不时有这个函数，不知道啥意思，
BOOL DisableThreadLibraryCalls(
HMODULE hLibModule
);
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.
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.

该函数在有许多DLL，频繁创建和删除线程，并且DLL不需要线程级消息如DLL_THREAD_ATTACH and DLL_THREAD_DETACH时的多线程应用中是很有效的优化。
