[Gdal-dev] Re: Using GDAL in Linux ANSI C

[Marc Lepage]

Is GDAL C code wrapped in C++, or C++ code wrapped in C? I'm curious
about which way it goes and the issues involved. I've typically wrapped
C with C++, but these days it seems more projects are going the other
way.

Brian,

Conveniently GDAL has C cover functions already!

If you look in gdal.h you will see the C API.  Most of the C++ method
documentation refers to the related C entry point, though there is no
documentation for the C entry points so you need to work it out by
examining the prototypes.

Best regards,
