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.
