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.
The hContext parameter is the handle of the context object
The phTPM parameter is a pointer to where the handle of the
TPM will be placed.
Tspi_Context_GetTpmObject returns TSS_SUCCESS on success,
otherwise one of the following values is returned:
hContext is not a valid handle.
An internal SW error has been detected.
One or more of the parameters is incorrect.
