NAME

       Tspi_TPM_ClearOwner - clear TPM ownership

SYNOPSIS

       #include <tss/platform.h>
       #include <tss/tcpa_defines.h>
       #include <tss/tcpa_typedef.h>
       #include <tss/tcpa_struct.h>
       #include <tss/tss_typedef.h>
       #include <tss/tss_structs.h>
       #include <tss/tspi.h>

       TSS_RESULT Tspi_TPM_ClearOwner(TSS_HTPM hTPM, TSS_BOOL fForcedClear);

DESCRIPTION

       Tspi_TPM_ClearOwner  wipes the TPM of everything but its endorsement key. It will wipe the
       SRK, so anything locked to the SRK will also disappear  when  this  command  is  executed.
       This  is the only way to be certain that keys are gone, as it is the only way to guarantee
       that nothing can keep a copy of the key. You must assert either physical presence or owner
       authorization in order to use this command.

PARAMETERS

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

   fForcedClear
       The  fForcedClear  parameter  is  used to tell whether this command is being executed with
       owner authorization or with physical presence. If FALSE, then TPM owner  authorization  is
       used. If TRUE, then physical presence is required to clear the TPM.

RETURN CODES

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

       TSS_E_INVALID_HANDLE
              hTPM is not a valid handle.

       TSS_E_INTERNAL_ERROR
              An internal SW error has been detected.
