ExitThreadDWORD
ExitThreadDWORD refers to the use of the Windows API function ExitThread when terminating a thread and specifying a 32‑bit exit code. In the Windows programming model, each thread can terminate by calling ExitThread, which accepts a single parameter of type DWORD that signifies the thread’s exit status. The exit code is a 32‑bit unsigned integer that can be retrieved by the thread‑creating process or by other threads that handle termination notifications. It is commonly used to communicate success, failure, or specific status information back to the caller.
The prototype for ExitThread is declared in the Windows header files as follows: VOID ExitThread(DWORD dwExitCode).
Typical use cases involve spawning worker threads that perform a computation and then exit with a status
Limitation: The exit code is only retrievable after the thread has finished; attempting to read the code
