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_Context_GetTpmObject(TSS_HCONTEXT hContext, TSS_HTPM* phTPM);

DESCRIPTION
       Tspi_Context_GetTpmObject retrieves the TPM object of a context. Only one instance of this object exists for a given context and implicitly
       represents a TPM owner. This function is normally called at the beginning of a program, right after the context is  established.  You  must
       have a context established prior to calling this function.

PARAMETERS
   hContext
       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.

RETURN CODES
       Tspi_Context_GetTpmObject returns TSS_SUCCESS on success, otherwise one of the following values is returned:

       TSS_E_INVALID_HANDLE
	      hContext is not a valid handle.

       TSS_E_INTERNAL_ERROR
	      An internal SW error has been detected.

       TSS_E_BAD_PARAMETER
	      One or more of the parameters is incorrect.
