WPUGetProviderPath function
The WPUGetProviderPath function retrieves the DLL path for the specified provider.
Syntax
int WPUGetProviderPath(
_In_ LPGUID lpProviderId,
_Out_ LPWSTR lpszProviderDllPath,
_Inout_ LPINT lpProviderDllPathLen,
_Out_ 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, in characters.
- lpErrno [out]
-
Pointer to the error code.
Return value
If no error occurs, WPUGetProviderPath returns zero. Otherwise, it returns SOCKET_ERROR, and a specific error code is available in lpErrno.
| Error code | Meaning |
|---|---|
|
The lpProviderId parameter does not specify a valid provider. | |
|
Either lpszProviderDllPath or lpErrno is not in a valid part of the user address space, or lpProviderDllPathLen is too small. |
Remarks
The WPUGetProviderPath function retrieves the DLL path for the specified provider. The DLL path is null-terminated and may contain embedded environment strings (such as %SystemRoot%). Thus, the string should be expanded prior to being used with LoadLibrary. For more information, see LoadLibrary.
