mitab_c_get_parts() should return 0 if a given feature has no geometry 
(i.e. is of type NONE).

There is no way to find out via the C API whether there is a .MAP file 
or not at the moment. You can only test individual features using 
mitab_c_get_parts().

Unfortunately this information is not available via the C API either. 
It's available in the TABMAPHeaderBlock object in the C++ classes but 
not directly accessible via the C API.
