TSS_RESULT Tspi_PcrComposite_GetPcrValue(TSS_HPCRS hPcrComposite, UINT32 ulPcrIndex,
UINT32* ulPcrValueLength, BYTE** rgbPcrValue);
DESCRIPTIONTspi_PcrComposite_GetPcrValue returns the digest value of a given PCR
index inside a PCR composite object.
PARAMETERS
hPcrComposite
Handle of the PCR composite object instance where a PCR value should be
returned.
ulPcrIndex
This parameter indicates the index of the PCR to read.
ulPcrValueLength
The length (in bytes) of the rgbPcrValue parameter.
rgbPcrValue
After successful completion this parameter recieves a pointer to the
memory block containing the PCR value of the PCR indicated by
ulPcrIndex.
RETURN CODESTspi_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.
CONFORMING TOTspi_PcrComposite_GetPcrValue conforms to the Trusted Computing Group
