I think we need to start tracking these issues in bugzilla.

I'm pretty sure that when he says "DLL" he means DLL on Windows. So the situation is that we cannot correctly use D shared libraries on Posix.

Yes, please file a bug report. Either to fix the documentation or implement the functions for Posix. The Posix functions can be implemented to only work for C shared libraries.

This code seems to only be fore ELF targets. This is not needed on Mac OS X, right? Bracketed sections are not needed on Mac OS X.

Thanks for the update. This looks interesting.

"DLL" is Windows
"shared library" is Linux/OSX/FreeBSD

Some people have a tendency to mix the terms. I like to call it "dynamic library" on all platforms.

Anyone else finds themself desiring a "loadSymbol( void * whateverReturnedByLoadLib, string name )" function?

Thanks for that! I'll make use of that for my C plugins.
