HANDLE hLookup
);
Parameters
- hLookup
[in] Handle previously obtained by calling the WSALookupServiceBegin (Windows Sockets) function.

Error code |
Description |
|---|---|
WSA_INVALID_HANDLE |
The handle is not valid. |
WSANOTINITIALIZED |
Ws2.dll has not been initialized. The application must first call the WSAStartup function 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 WSALookupServiceNext call to return immediately.
Notes for Bluetooth
Bluetooth clients use WSALookupServiceBegin (Windows Sockets), WSALookupServiceNext (Windows Sockets), and WSALookupServiceEnd to 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.
