NAME
     Tspi_TPM_StirRandom - add entropy to the TPM random number generator

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_StirRandom(TSS_HTPM hTPM, UINT32 ulEntropyDataLength, BYTE* rgbEntropyData);

DESCRIPTION
     Tspi_TPM_StirRandom adds entropy to the TPM random number generator for the
     purpose  of  generating  better random numbers. The entropy variable should
     assigned an appropriately seeded random  number  before  this  function  is
     called.

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.

   ulEntropyDataLength
     The ulEntropyDataLength parameter is the length in bytes of the rgbEntropy-
     Data parameter.

   rgbEntropyData
     The rgbEntropyData parameter is a pointer to the entropy data.

RETURN CODES
     Tspi_TPM_StirRandom 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_StirRandom conforms to the Trusted Computing Group Software Speci-
     fication version 1.1 Golden
