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.
 

CONFORMING TO

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