Question

I have a binary file that is really a stack of files, the format is:

lengh_of_subfile,subfile

length_of_subfile is a 64-bit integer. I can read the long no problem but when I try to create a buffer for the subfile I get compile errors saying it cannot be read at compile time. What am I missing? I’ve written an identical extraction tool in erlang, PHP and C#… D is throwing me for a loop.

void main(string args[]) {
    Stream file = new BufferedFile(args[1], FileMode.In);
    int counter = 0;
    while(file.position < file.size) {
        ulong len;
        file.read(len);
        ubyte[len] ogg;
        file.read(ogg);
        string outname = getcwd() ~ "/" ~ to!string(counter) ~ ".ogg";
        Stream oggout = new BufferedFile(outname, FileMode.OutNew);
        oggout.write(ogg);
        writefln("Creating file " ~ to!string(counter) ~ ".ogg");
        counter++;
    }   
}

Answer 1

Instead of

        ubyte[len] ogg;

write

        ubyte[] ogg = new ubyte[len];
