hey /prog/

im writing a lisp interpreter from scratch in C (or rather trying to) and i dont know how to represent a general lisp object . i also dont know how to implement ˝lambda˝ and ˝apply˝ , or rather a function which generates a function and returns its address.

any ideas /prog/ ?
is it even possible to write a function that generates a function in C ?
and how the fuck does one make a struct member with undefined lenght/variable ?

Why would you be writing a Lisp interpreter in C when you don't know anything about Lisp, C or how to program?
If you're writing an interpreter, you don't `generate a function in C', you generate a Lisp function object.
And you store the length of the member in the struct, and either store a pointer to the alloc'ed data, or use a flexible array member.
