Include a C API - Githubissues

GoogleCodeExporter commented 8 years ago

This is an enhancement.

Adding a C API to libkml would enable the library to be used by C
programmers with no knowledge of C++.

This is an enhancement request.  KML and the libkml dom are
inherently object-oriented so pure C is a challenge.

I have no doubt that it is a challenge! You might be interested to note that it 
is a
challenge that the GEOS project (http://geos.refractions.net) has risen to. 
This is a
complex object-oriented C++ geometry engine that has a very useful C interface
wrapper (http://download.osgeo.org/geos/doxygen/c_iface.html).

Could you support iphone object c?

No plans to support Objective C. ObjC itself has support for calling C++ static
libraries, so you may want to try that.

Awesome that you're taking a crack at iphone!  Wish I had the bandwidth myself
for that as well as android ndk.

Maybe you need to back up a step and build a simple hello world with expat.
Just to keep this all complicated (or maybe make it easier) note that expat 
itself
is all plain C.

Enjoy and keep us posted!
