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.
