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 vari-
       able 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 rgbEntropyData 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 Specification version 1.1 Golden
