I have created the following C library for reading an image:

typedef struct {
    unsigned int height;
    unsigned int width;

    unsigned char* red; //length=height*width
    unsigned char* green;
    unsigned char* blue;
} Contents;

Contents readJPEGFile(const char* inFilename);

I can't really find any info using arrays and structs with the Foreign Function Interface. How would I proceed to be able to use my library in Haskell?

I tried to use the following example as a base: http://therning.org/magnus/archives/315 but then the hsc file was compiled down to a hs file that only contained the above c-code and nothing more (and of course it can't be compiled).

haskell word-wrap ffi
