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.
