Provides services to retrieve values from a capsule's FMP Payload Header.
|
|
The structure is not included in the library class. Instead, services are
|
|
provided to retrieve information from the FMP Payload Header. If information
|
|
is added to the FMP Payload Header, then new services may be added to this
|
|
library class to retrieve the new information.
