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>

       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_Get-
       Capability(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
