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 dis-
       appear  when this command is executed.  This is the only	way to be cer-
       tain that keys are gone,	as it is the only way to guarantee that	 noth-
       ing  can	 keep a	copy of	the key. You must assert either	physical pres-
       ence 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  be-
       ing  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.
