VOID ExitThread(
DWORD dwExitCode // exit code for this thread
);
Parameters
dwExitCode
Specifies the exit code for the calling thread. Use the GetExitCodeThread function to retrieve a thread's exit code.
Return Values
This function does not return a value.
Remarks
ExitThread is the preferred method of exiting a thread. When this function is called (either explicitly or by returning from a thread procedure), the current thread's stack is deallocated and the thread terminates. The entry-point function of all attached dynamic-link libraries (DLLs) is invoked with a value indicating that the thread is detaching from the DLL.
If the thread is the last thread in the process when this function is called, the thread's process is also terminated.
The state of the thread object becomes signaled, releasing any other threads that had been waiting for the thread to terminate. The thread's termination status changes from STILL_ACTIVE to the value of the dwExitCode parameter.
Terminating a thread does not necessarily remove the thread object from the operating system. A thread object is deleted when the last handle to the thread is closed.
