Question on pointers and importing of shared libraries

[methodic]

What is the method of referencing/retrieving the data in a (char **) pointer? I have successfully used (get-string) when trying to reference a (char *), but no such luck with the other. I tried various calls to address with no luck. Is this even possible?



Thanks in advance!

look at the last row in both tables at the end of the chapter. Note that in C, char ** foo is the same as char * foo[].



If you are not familiar with the C language and how pointers in C work, try to find an experienced C programmer to help you.

I just wrote a tutorial on using newlisp's ffi: http://www.artfulcode.net/articles/using-the-newlisp-ffi/">http://www.artfulcode.net/articles/usin ... wlisp-ffi/">http://www.artfulcode.net/articles/using-the-newlisp-ffi/. That might be worth looking at.
