There is no interface for that. You need to access the ExifEntry->data
directly, i.e.

e =3D exif_entry_new ();
exif_content_add_entry (c, e);
e->tag =3D EXIF_TAG_GPS_...;
e->format =3D EXIF_FORMAT_SHORT;
e->components =3D 1;
e->size =3D ...;
e->data =3D malloc (...):
exif_set_short (e->data, byte_order, ...);

Or similar (I don't know what format the individual tags have -> EXIF
specification).
