NAME
       Tspi_TPM_DirRead	- Read a Data Integrity	Register

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_DirRead(TSS_HTPM hTPM,	      UINT32 ulDirIndex,
				   UINT32*  pulDirDataLength, BYTE** prgbDirData);

DESCRIPTION
       Tspi_TPM_DirRead	reads a	data integrity register. DIRs are non-volatile
       (persistent across reboots) memory areas	maintained by the TPM.

PARAMETERS
   hTPM
       The hTPM	parameter is used to specify the handle	of the TPM object.

   ulDirIndex
       The ulDirIndex parameter	is the index of	the DIR	to read. To query  the
       TPM  for	the number of DIR registers it supports, use Tspi_TPM_GetCapa-
       bility(3).

   pulDirDataLength
       The pulDirDataLength parameter receives the  length  in	bytes  of  the
       prgbDirData parameter.

   prgbDirData
       The  prgbDirData	 parameter receives a pointer to memory	containing the
       DIR data.

RETURN CODES
       Tspi_TPM_DirRead	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_DirRead	conforms to the	Trusted	Computing Group	Software Spec-
       ification version 1.1 Golden
