TSS_RESULT Tspi_PcrComposite_GetPcrValue(TSS_HPCRS hPcrComposite,    UINT32 ulPcrIndex,
                                         UINT32*   ulPcrValueLength, BYTE** rgbPcrValue);


Tspi_PcrComposite_GetPcrValue returns the digest value of a given PCR index inside a PCR composite object.



Handle of the PCR composite object instance where a PCR value should be returned.


This parameter indicates the index of the PCR to read.


The length (in bytes) of the rgbPcrValue parameter.


After successful completion this parameter recieves a pointer to the memory block containing the PCR value of the PCR indicated by ulPcrIndex.

Return Codes

Tspi_PcrComposite_GetPcrValue returns TSS_SUCCESS on success, otherwise one of the following values are returned:

TSS_E_INVALID_HANDLE - Either hPcrComposite or ulPcrIndex is an invalid parameter.

TSS_E_INTERNAL_ERROR - An error occurred internal to the TSS.
