It's been a while since I have worked with this API, but the
documentation on the page you reference says that you allocate the info
element options template using fbInfoElemntAllocTypeTemplate(), and then
you can register it using fbSessionAddTemplate().  This function can
take FB_TID_AUTO as its tid argument, and will return the actual
template ID assigned.  You would call this twice, once as internal, and
once as external.  Set the fbuf's internal and external templates to
these IDs (using fBufSet{Internal,External}Template(), and then call
fbInfoElementWriteOptionsRecord, almost certainly using the internal
template ID as the tid argument.
