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 func-
       tion 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	rgbEn-
       tropyData 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
