This function retrieves the DLL path for the specified provider.
int WPUGetProviderPath(LPGUID lpProviderId,LPWSTR lpszProviderDllPath,LPINT lpProviderDllPathLen,LPINT lpErrno );
Parameters
- lpProviderId
[in] Locally unique identifier of the provider. This must be a value obtained by using WSCEnumProtocols. - lpszProviderDllPath
[out] Pointer to a buffer containing a string that identifies the provider DLL's path. This path is a null-terminated string and any embedded environment strings (such as %SystemRoot%) have not been expanded. - lpProviderDllPathLen
[in, out] Size of the buffer pointed to by lpszProviderDllPath. - lpErrno
[out] Pointer to the error code.
Return Values
If no error occurs, WPUGetProviderPath returns zero. Otherwise, it returns SOCKET_ERROR, and a specific error code is available in lpErrno.
The following table shows the possible error codes.
| Error value | Description |
|---|---|
| WSAEINVAL | The lpProviderId does not specify a valid provider. |
| WSAEFAULT | Either lpszProviderDllPath or lpErrno is not in a valid part of the user address space, or lpProviderDllPathLen is too small. |
Remarks
This function retrieves the DLL path for the specified provider. The DLL path is null-terminated and can contain embedded environment strings, such as %SystemRoot%. Thus, the string should be expanded prior to being used with LoadLibrary.
Requirements
