g-code parsers

In anticipation of getting the big gantry mill mechanically done
I have been writing the control code in c. I am still waiting for some
spiral bevel gears and angular contact bearings for the
twin ball screw transmissions I have built.

I began today on a g-code parser function. I want it to be very non-hardware
specific- just a function that puts the commands and coordinates in a nice
neat set of little arrays. Other functions will use that for hardware
specific commands (to servo card with arc or NURBS interpolation). Most of
those are written.

I can do this but I really feel like I am reinventing the wheel.
Parsing is noy the most fun code to write either. A gazzillion
string tests.

I wonder if anyone can point me to an already written c function that does
this? I am not a c++ type but could be if it
happens to be of that implementation.

Thanks
