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	gener-
       ating 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	 allo-
       cates 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
       Specification version 1.1 Golden
