I'm reading the CSUG to learn the FFI of chez-scheme. So I may have some beginner's error.
I just want to know is there some question of FFI.
C have some type of data, just like char, float, double, int, functions, struct, union, or enumeration.
But they are not existed in scheme.
There is number, list, character, string and symbol. Or the defstruct macro
Is there some not compatible between their data type. If it's exit, What's the solution of the FFI.
