have a context established prior to calling this function.

- The hContext parameter is the handle of the context object (already existing).
- phTPM
- The phTPM parameter is a pointer to where the handle of the TPM will be placed.

of the following values is returned:
- TSS_E_INVALID_HANDLE
- hContext is not a valid handle.
- TSS_E_INTERNAL_ERROR
