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/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 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
