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.

Remarks

This method copies an IPortableDeviceValues interface into an existing buffer. If you want to allocate a new buffer, use GetBufferFromIPortableDeviceValues.
