WPUCloseThread function
The WPUCloseThread function closes a thread opened with a call to WPUOpenCurrentThread.
Syntax
INT WSPAPI WPUCloseThread( _In_ LPWSATHREADID lpThreadId, _Out_ LPINT lpErrno );
Parameters
- lpThreadId [in]
-
Pointer to a WSATHREADID structure that identifies the thread context. This structure must have been initialized by a previous call to WPUOpenCurrentThread.
- lpErrno [out]
-
Pointer to the error code.
Return value
If no error occurs, WPUOpenCurrentThread returns zero. Otherwise, it returns SOCKET_ERROR, and a specific error code is available in lpErrno.
| Error code | Meaning |
|---|---|
|
A successful WSPStartup call must occur before using this function. |
Remarks
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.
