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.

Question about how to determine if there is no geometry.

2007-08-30T23:41:13Z

Greetings all who takes part in developing such great lib as mitab!

My question is how using mitab_c_api i can determine that there is no geometry at all, I mean, no MAP file but only tab and dat present.
I use Borland C++Builder 5 and lib version i have dounloaded about week ago. My future application is to read MI files and to export it to Oracle.
Also I want to know precision of coords returned, 'cause i will pass it through SQL (or PL/SQL, i've not decided yet) scripts, and want to know whether this idea is good.

Thank in advance to all who will help. Sorry for my awful english.
