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.
