This file declares GUIDed section extraction protocol.
|
|
|
|
This interface provides a means of decoding a GUID defined encapsulation
|
|
section. There may be multiple different GUIDs associated with the GUIDed
|
|
section extraction protocol. That is, all instances of the GUIDed section
|
|
extraction protocol must have the same interface structure.
