Write struct to file

[Andrej Mitrovic]

Well first I'd recommend not allocating the struct on the heap. Then you can do:

import std.stdio;

struct nagger
{
    string name;
    int age;
    double weight;
    string msg;
}

void main()
{
    nagger lal;
    lal.name   = "name";
    lal.age    = 23;
    lal.weight = 108.5;
    lal.msg    = "msg";

    auto file = File("test.bin", "w");
    auto writeBytes = fwrite(&lal, byte.sizeof, lal.sizeof, file.getFP());
    file.close();

    nagger dup;
    file = File("test.bin", "r");
    auto readBytes = fread(&dup, byte.sizeof, dup.sizeof, file.getFP());

    assert(lal == dup);
}

This doesn't work for heap-allocated structs.
