This should be simple? All I want to do is load an entire

So far, all google searches for "dlang binary file read" end 
up not working for me.

Thank you.

import std.file : read;
auto bytes = read("filename");

This gives you a void[], which you can cast to ubyte[] or 
char[] or whatever you need.

Or he could do readText() which returns a string, which in turn 
will give a proper char array when casted.

Actually ignore the casting thing, looking at readText it takes a 
template parameter.

So:

char[] a = readText!(char[])("filename");
