IWpdSerializer::WriteIPortableDeviceValuesToBuffer method
The WriteIPortableDeviceValuesToBuffer method serializes an IPortableDeviceValues interface to a caller-allocated byte array.
Syntax
HRESULT WriteIPortableDeviceValuesToBuffer(
[in] DWORD dwOutputBufferLength,
[in] IPortableDeviceValues *pResults,
[out] BYTE *pBuffer,
[out] DWORD *pdwBytesWritten
);
Parameters
-
dwOutputBufferLength [in]
-
DWORD that specifies the size of pBuffer, in bytes.
-
pResults [in]
-
Pointer to an IPortableDeviceValues interface to serialize.
-
pBuffer [out]
-
Pointer to a caller-allocated buffer. To learn the size of the required buffer, call GetSerializedSize.
-
pdwBytesWritten [out]
-
Pointer to a DWORD that indicates the number of bytes that was actually written to the caller-allocated buffer.
Return value
The method returns an HRESULT. Possible values include, but are not limited to, those in the following table.
| Return code | Description |
|---|---|
|
The method succeeded. |
|
A required pointer argument was NULL. |
|
