Re: [Caml-list] reading bytes into c-defined structs

[Shishir Ramam <sramam@gmail.com>]

Henri,
One way to do this would be to 
1. Write a C function that will actually read the bytes and populate the C 
    data structure, and return that data structure. 
2. Put this function in your idl file, and CamlIDL will generate the necessary
    code to make the C call *and* do the necessary translation into the Ocaml 
    record.
3. All you then have to do it call the function in Ocaml whenever you'd like to 
    read a packet.

This is pretty neat, and works well in my experience.

Hope this helps.
