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.
-
Tspi_PcrComposite_GetPcrValue conforms to the Trusted Computing Group
Software Specification version 1.1 Golden
