[Liblas-devel] c tutorial needed

[Howard Butler]

The best C API tutorials are the utilities, as they are almost all  
written in C.

<http://liblas.org/browser/apps/las2las.c>

<http://liblas.org/browser/apps/lascommon.c>

These two probably provide the most coverage the C API. Otherwise the  
place to look is the liblas.h header, which while it does not have any  
examples, is very complete <http://liblas.org/doxygen/a00033.html>

HTH,

Howard
