Hi,

what do I have to do, if I want to add a new function to newlisp, with an implementation on the C-side of things?

I guess I've found out, that, e.g. p_and in newlisp.c is the implementation of and in newlisp. But I'm missing the link between the two.

Where do I have to look?

TIA,

Ingo

The easiest method to expand newLISP is to write a C-library and then import the function. newLISP's C-library interface is very tight and gives you as much performance as a built-in.

Look into chapter 19: http://newlisp.org/DesignPatterns.html#extending

for details. If you need help, how to compile and import your C-function, let me know.
