This function is called to free the handle after previous calls to WSALookupServiceBegin (Windows Sockets)and WSALookupServiceNext (Windows Sockets).
Syntax
INT WSALookupServiceEnd( HANDLE hLookup ); |
Parameters
- hLookup
-
[in] Handle previously obtained by calling the WSALookupServiceBegin (Windows Sockets)function.
Return Value
If the operation was successful, the return value is zero. If an error occurs, the value SOCKET_ERROR is returned, and a specific error number can be retrieved by calling the WSAGetLastErrorfunction. The following table shows a list of possible error codes.
| Error code | Description |
|---|---|
|
WSA_INVALID_HANDLE |
The handle is not valid. |
|
WSANOTINITIALIZED |
Ws2.dll has not been initialized. The application must first call the WSAStartupfunction before calling any Windows Sockets functions. |
|
WSA NOT ENOUGH MEMORY |
There was insufficient memory to perform the operation. |
Remarks
If you call this function from another thread while an existing WSALookupServiceNext (Windows Sockets)is blocked, the end call will have the same effect as a cancel and will cause the WSALookupServiceNextcall to return immediately.
Notes for Bluetooth
Bluetooth clients use WSALookupServiceBegin (Windows Sockets), WSALookupServiceNext (Windows Sockets), and WSALookupServiceEndto discover the existence of a particular service on the Bluetooth RFCOMM server. Queries can be done for local and remote addresses, although for RFCOMM a client can connect only to remote addresses.
