[Chicken-users] foreign: Why is passing structs as arguments and return-types not supported?

[Kristian Lein-Mathisen]

Hi guys!

Reading the chicken docs on foreign, you'll find:

> Structs cannot be directly passed as arguments to foreign functions, nor can they be result values. (http://api.call-cc.org/doc/foreign/types#def:struct)

Pointers to structs are supported, but not structs-by-value. I am wondering if there are technical reason why this is the case, or if it's simply a "missing feature". If it simply hasn't been implemented, I will see if I can make this feature.

Thank you,

K.
