Tspi_TPM_DirWrite - write to a Data Integrity Register

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

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.

       Tspi_TPM_DirWrite - write to a Data Integrity Register

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  regis‐
       ters it supports, use Tspi_TPM_GetCapability(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.

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.

Tspi_TPM_GetCapability(3), Tspi_TPM_DirRead(3).
