Hello John
Thanks for the quick answer. The link to the post by Hal Finney was helpful too.
But my question still doesn't get fully answered.
As I mentioned in my mail, the TPM Main Specification, Part 3 Commands v1.2
defines as one of the output of TPM Quote command:
"TPM_PCR_COMPOSITE pcrData -- A structure containing the same indices as target
PCR, plus the corresponding current PCR values.
I do not find this output in the implementation of Tspi_TPM_Quote function."
As written in the last note of Hal Finney's post, I'm able to retrieve each PCR
value one by one using Tspi_PcrComposite_GetPcrValue() function.
But if the TPM Main Specification defines the TPM_PCR_COMPOSITE structure
(which contains all the quoted PCR indexes and their values)
as an output, why the Tspi_TPM_Quote function does not provide me that?
Best regards
Sansar

I'm not sure how to answer a should question, but a good posting
by Hal Finney describing the output is here:

It is what it is.
