TPMLIB_ChooseTPMVersion - Choose the version of the TPM

The TPMLIB_ChooseTPMVersion() function is used to choose the version of the TPM, either a TPM 1.2 or TPM 2. This function must be called before TPMLIB_MainInit() is called and will otherwise return an error. This function may be called again once TPMLIB_Terminate() has been called. If this function is not called, the last chosen TPM version will be started with TPMLIB_MainInit(). If this function is not called, a TPM 1.2 will be used.

TPM_SUCCESS The version of the TPM was chosen successfully. TPM_FAIL The choice of the TPM was wrong, or TPMLIB_MainInit() has already been called. For a complete list of TPM error codes please consult the include file libtpms/tpm_error.h
