This function terminates the use of a particular Windows Sockets name space service provider.
Syntax
int NSPCleanup(
LPGUID lpProviderId
);
Parameters
- lpProviderId
[in] Pointer to the GUID of the name-space provider that is to be terminated.
Return Value
If no error occurs, this function returns a value of NO_ERROR (zero). Otherwise, SOCKET_ERROR (–1) is returned and the provider must set the appropriate error code using SetLastError.
The following table shows the available error codes.
| Value | Description |
|---|---|
WSAEINVAL |
The lpProviderId does not specify a valid provider. |
WSA_NOT_ENOUGH_MEMORY |
Not enough free memory available to perform this operation. |
Remarks
This function is called when an application is finished using a Windows Sockets name space service provider. The function deregisters a particular name-space provider and allows the transport service provider to free any of the name-space provider's allocated resources.
The NSPStartup function must be called successfully before using any name-space providers. It is permissible to make more than one NSPStartup call. However, for each call, a corresponding NSPCleanup call must also be issued. Only the final NSPCleanup for the service provider does the actual cleanup; the preceding calls simply decrement an internal reference count in the service provider.
This function should not return until the name space service provider DLL can be unloaded from memory.
