Encoding C Structs

Question

I have a struct defined like follows as part of an object. I'm trying to encode this for use with NSCoder with the aim of saving as well as Undo/Redo functionality.

struct myCol {
    float rd;
    float grn;
    float blu;
    float alp;
} toolColor;

So, there are methods to encode e.g. -encodeBool:, -encodeFloat:, -encodeObject: etc. But how do you do this for a struct?

Answer 1

I think you should consider you struct myCol as memory buffer and encode it by something like encodeBytes function. Buffer length = size of your struct
