hTPM The hTPM parameter is used to specify the handle of the TPM object. ulDirIndex The ulDirIndex parameter is the index of the DIR to write. To query the TPM for the number of DIR registers it supports, use Tspi_TPM_Get- Capability(3). ulDirDataLength The ulDirDataLength parameter is the length in bytes of the rgbDirData parameter. rgbDirData The rgbDirData parameter is a pointer to memory containing the data to be written to the DIR. RETURN CODES
Tspi_TPM_DirWrite 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
