       TSS_RESULT Tspi_TPM_TakeOwnership(TSS_HTPM hTPM, TSS_HKEY hKeySRK,
                                         TSS_HKEY hEndorsementPubKey);

DESCRIPTION

       Tspi_TPM_TakeOwnership  takes  ownership  of  a  TPM.  Taking  ownership is the process of
       inserting a shared secret into the TPM. The owner of the TPM (anyone who knows the  shared
       secret) has the right to perform special operations.

PARAMETERS

   hTPM
       The hTPM parameter is used to specify the handle of the TPM object.

   hKeySRK
       The hKeySRK parameter is the handle to the object representing the TPM's Storage Root Key.

   hEndorsementPubKey
       The  hEndorsementPubKey  parameter  is  the  handle  to  the object representing the TPM's
       endorsement public key. This key is required for encrypting the secret of the SRK and  the
       TPM  owner secret. If NULL, the TSP internally queries the TPM for that endorsement public
       key.

RETURN CODES

       Tspi_TPM_TakeOwnership returns TSS_SUCCESS on success,  otherwise  one  of  the  following
       values is returned:

       TSS_E_INVALID_HANDLE
              Either the TPM or one of the key handles is not valid.

       TSS_E_INTERNAL_ERROR
              An internal SW error has been detected.

CONFORMING TO

       Tspi_TPM_TakeOwnership  conforms  to  the  Trusted  Computing Group Software Specification
