FreeLibraryAndExitThread function (libloaderapi.h)
Decrements the reference count of a loaded dynamic-link library (DLL) by one, then calls ExitThread to terminate the calling thread. The function does not return.
Syntax
void FreeLibraryAndExitThread(
[in] HMODULE hLibModule,
[in] DWORD dwExitCode
);
Parameters
[in] hLibModule
A handle to the DLL module whose reference count the function decrements. The LoadLibrary or GetModuleHandleEx function returns this handle.
Do not call this function with a handle returned by either the GetModuleHandleEx function (with the GET_MODULE_HANDLE_EX_FLAG_UNCHANGED_REFCOUNT flag) or the GetModuleHandle function, as they do not maintain a reference count for the module.
[in] dwExitCode
The exit code for the calling thread.
Return value
None
Remarks
The FreeLibraryAndExitThread function allows threads that are executing within a DLL to safely free the DLL in which they are executing and terminate themselves. If they were to call FreeLibrary and ExitThread separately, a race condition would exist. The library could be unloaded before ExitThread is called.
