The WPUCloseThread function closes a thread opened with a call to WPUOpenCurrentThread.
INT WSPAPI WPUCloseThread (
LPWSATHREADID lpThreadId,
LPINT lpErrno
);
The WPUCloseThread function is used in a layered service provider to deallocate the resources that were initiated in a call by the WPUOpenCurrentThread function. The WSATHREADID structure in the lpThreadId is the thread to deallocate.
Every call to WPUOpenCurrentThread must have a call to WPUCloseThread. These two functions are used when the overlapped functions, such as WSPSend, are called in a lower layer of the service provider than the current thread.
If no error occurs, WPUOpenCurrentThread returns the zero. Otherwise, it returns SOCKET_ERROR, and a specific error code is available in lpErrno.
