Tspi_PcrComposite_GetPcrValue(3)
NAME
Tspi_PcrComposite_GetPcrValue - get the digest value of a given PCR
index inside a PCR composite object.
SYNOPSIS
#include <tss/platform.h> #include <tss/tcpa_defines.h> #include <tss/tcpa_typedef.h> #include <tss/tcpa_struct.h> #include <tss/tss_typedef.h> #include <tss/tss_structs.h> #include <tss/tspi.h> 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.
