ippStsStreamEnd

Stop at the stream boundary

ippStsStreamEnd tells a data-compression caller that the current compressed stream has completed. It should normally terminate the decode loop for that member even when input bytes remain. Remaining bytes can belong to a container trailer, another concatenated member, or unrelated following data.

Continuing to feed the completed decoder state as though more output were required can turn valid trailing data into a misleading corruption error.

What to verify

Record total input consumed and output produced at the exact stream-end transition.
Validate any checksum or trailer required by the surrounding format.
Decide explicitly whether concatenated streams are allowed and reinitialize state before processing the next one.
Distinguish stream end from source exhaustion: a short source buffer does not prove that the logical stream ended.
