Description

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.

Errors

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.
