VSS_ALTERNATE_WRITER_STATE enumeration
The VSS_ALTERNATE_WRITER_STATE enumeration is used to indicate whether a given writer has an associated alternate writer. The existence of an alternate writer is set during writer initialization by CVssWriter::Initialize.
Currently, the only supported value for a method taking a VSS_ALTERNATE_WRITER_STATE argument is VSS_AWS_NO_ALTERNATE_WRITER.
