digitalmars.D - Large file support?

I could not find any way to open large files using D/Phobos streams.  I 
wound up writing a little C turdlet to handle this.

Since Phobos calls the C library, I think adding support for this could 
be as simple as compiling dmd with _FILE_OFFSET_BITS defined to 64.

I'm not sure, but I think it's presently defined as size_t; which is aliased to either long or int depending on the system. I don't think they used uint or ulong...

It refused to open the file at all with a "File too large" error.

Have you tried using MmFileStream? Seems to me that, or BufferedFile, would be the way to go. FWIW, Tango has some rather sophisticated file-IO that is up to the task for big files as well. -- - EricAnderton at yahoo

whatever opening a 6GB file. Never heard of MmFileStream, is there doc for it somewhere? Thanks, Jose.

I had never noticed that. And I was using SliceStream, too. I'm embarrassed.

Don't be. You should see how many times I've made mistakes on these forums this month. People are probably remembering me by name so they can ignore my posts... : p Best of luck then.
