    Struct (with pointer) to byte array


    I have a struct that I need to convert to a byte(=char) array. Normally, I know how to do that using memcpy() but in this case the struct contains a pointer that I use to allocate memory dynamically elsewhere is my program.

    Something like:

    struct my_struct {
        int size;
        int num;
        int *list;
    } sb;
    and later on:
    sb.list = (int*)malloc(some_var);
    Is this even possible? If it is, what approach should I follow?

    first convert struct contents without pointer, then convert memory pointed by the pointer
    All problems in computer science can be solved by another level of indirection,
    except for the problem of too many layers of indirection.
