NAME
       Tspi_TPM_DirWrite - write to 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_DirWrite(TSS_HTPM hTPM,	      UINT32 ulDirIndex,
				    UINT32   ulDirDataLength, BYTE*  rgbDirData);

DESCRIPTION
       Tspi_TPM_DirWrite  writes  a  data integrity register. You need to know
       the DIR index and data you wish to write	to the DIR prior to using this
       command.

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 write. To query the
       TPM for the number of DIR registers it supports,	use  Tspi_TPM_GetCapa-
       bility(3).

   ulDirDataLength
       The  ulDirDataLength parameter is the length in bytes of	the rgbDirData
       parameter.

   rgbDirData
       The rgbDirData parameter	is a pointer to	memory containing the data  to
       be written to the DIR.

RETURN CODES
       Tspi_TPM_DirWrite  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_DirWrite conforms to  the  Trusted  Computing  Group  Software
       Specification version 1.1 Golden
