Serializes a package that is represented by a package object.

Syntax

HRESULT WritePackageToStream(
  IOpcPackage     *package,
  OPC_WRITE_FLAGS flags,
  IStream         *stream
);

Parameters

package

A pointer to the IOpcPackage interface of the package object that contains data to be serialized.

flags

The value that describes the encoding method used in serialization.

stream

A pointer to the IStream interface of the stream where the package object data will be written.

Return Value

The method returns an HRESULT. Possible values include, but are not limited to, those in the following table.

Return code Description
S_OK
The method succeeded.
E_INVALIDARG
The value passed in the flags parameter is not a valid OPC_WRITE_FLAGS enumeration value.
E_NOTIMPL
This method is not implemented for this version of Windows.
E_POINTER
At least one of the stream and package parameters is NULL.
IStream interface error
An HRESULT error code from the IStream interface.
Package Consumption error

Remarks

Do not use a stream to serialize package data when the same stream is being used to deserialize a package, because the attempt may result in undefined behavior.
