NAME
       Tspi_TPM_PcrExtend - extend a PCR register and optionally write the PCR
       event log.

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_TPM_PcrExtend(TSS_HTPM	    hTPM,	       UINT32 ulPcrIndex,
				     UINT32	    ulPcrDataLength,   BYTE*  pbPcrData,
				     TSS_PCR_EVENT* pPcrEvent,
				     UINT32*	    pulPcrValueLength, BYTE** prgbPcrValue);

DESCRIPTION
       Tspi_TPM_PcrExtend extends a PCR	register and writes the	PCR event  log
       if one is supplied by the user.

PARAMETERS
   hTPM
       The hTPM	parameter is used to specify the handle	of the TPM object. The
       command to get the TPM to test itself will be sent here.

   ulPcrIndex
       The ulPcrIndex parameter	is the index of	the PCR	to extend.

   ulPcrDataLength
       The ulPcrDataLength parameter is	the length in bytes of	the  pbPcrData
       parameter.

   pbPcrData
       The  pbPcrData parameter	is a pointer to	data which will	be used	in the
       extend operation.

   pPcrEvent
       The pPcrEvent parameter is the TSS_PCR_EVENT structure to be passed  to
       the  TCS	 to record the extend event. If	pPcrEvent is not NULL, the ap-
       plication should	fill out the members of	the structure  that  it	 cares
       about.

   pulPcrValueLength
       The  pulPcrValueLength  parameter  receives  the	length in bytes	of the
       prgbPcrValue parameter.

   prgbPcrValue
       The prgbPcrValue	receives a pointer to the memory block containing  the
       PCR data	after the extend operation.

RETURN CODES
       Tspi_TPM_PcrExtend returns TSS_SUCCESS on success, otherwise one	of the
       following values	is returned:

       TSS_E_INVALID_HANDLE
	      hTPM is not a valid handle.

       TSS_E_INTERNAL_ERROR
	      An internal SW error has been detected.

       TSS_E_BAD_PARAMETER
	      One or more parameters is	bad.

CONFORMING TO
       Tspi_TPM_PcrExtend conforms to the  Trusted  Computing  Group  Software
       Specification version 1.1 Golden
