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