Re: Can this be done? (loading extensions from dlls / so's at runti me)

[Martin Spernau <martin@...>]

I think Asko was searching for a more generic libary loading than 
loadlib suppliues (which loads lua-specific extensions, that handle the 
dll loading and function exporting)

Well. alll this has actually been discussed before, but I have yet to 
see a solution that loads dll's generically like say VisualBasic does 
with the 'declare'

I believe ther is a generic function loader for Linux, part of the 
luagnome project (http://luagnome.free.fr/luaffi.php3)

I've yet to see something like this for Windows, tho, and would be very 
intersted in such.

The LuaCOM http://www.tecgraf.puc-rio.br/~rcerq/luacom/ might well suit 
some purposes here...
