Tspi_TPM_GetRandom(3)	    Library Functions Manual	   Tspi_TPM_GetRandom(3)

		    TCG Software Stack Developer's Reference

NAME
     Tspi_TPM_GetRandom - generate a random number on the TPM

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_GetRandom(TSS_HTPM hTPM, UINT32 size, BYTE** random);

DESCRIPTION
     Tspi_TPM_GetRandom  gets a good random number for the purpose of generating
     symmetric keys, nonces, or seeding a random number generator.

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.

   size
     The size parameter is the number of random bytes requested.

   random
     The  random  parameter  is  a pointer to memory containing the random data.
     This is where the generated number goes. Because this internally  allocates
     memory, Tspi_Context_FreeMemory should also be used.

RETURN CODES
     Tspi_TPM_GetRandom  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_GetRandom conforms to the Trusted Computing Group Software  Speci-
     fication version 1.1 Golden
