Exception for large file in FileConduit.position()

Same problem can be expected in TempFile:559

File support for Posix is currently 32bit only. The 64bit headers need to be resolved first, which Sean is aware of

with 64bit you meant the filesystem API, not the OS?

Just to clarify, i have this problem on a x86 32 bit linux ubuntu 8.04 with dmd.

I believe largefile support is a combination of the FS supporting it (most do these days), and the OS/kernel supporting it (most do these days), but there is no POSIX 64 bit standard, so this is done by mapping various combinations filefoo and filefoo64 calls onto either the same underlying system calls, or stuff like foo(2) - this all depends on the OS, for instance is Solaris different from Linux.

So to answer your last question, Tango's API doesn't properly support 64 bit filesystems.

As mentioned elsewhere, best bet is to somehow pick up the relevant C define and translate it to a D version or const value that can be checked in D source.

It would be sweet if the compilers had a way to do this, but for DMD for instance, we probably can check when creating/modifying dmd.conf, and set the appropriate version.

One of these days I'll collect my thoughts on this in one place ...

FWIW, #656 is the original large file system ticket I think.

This should be fixed with the largefile changes I checked in today. However, I don't want to switch Tango over to using the new routines until they've been verified to work. To do this, set USE_LARGEFILE64 to true in tango.stdc.posix.config.
