FreeLibraryAndExitThread function

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 WINAPI FreeLibraryAndExitThread(
  _In_ HMODULE hModule,
  _In_ DWORD   dwExitCode
);

Parameters

hModule [in]

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 the GetModuleHandle function, since this function does not maintain a reference count for the module.

dwExitCode [in]

The exit code for the calling thread.

Return value

This function does not return a value. Invalid module handles are ignored.

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.
