That is a C/Invoke addon for Io, based on Trevor Fancher's CFFI addon.

To get it:

cd my_io_installation/addons
git clone git://github.com/fredreichbier/io-cinvoke.git CInvoke

It does support (in theory):

• dynamic library loading on all systems supported by C/Invoke
• dynamic function calling
• C structure access
• Io callback functions

Its dependencies:

• C/Invoke >= 1.0 (http://www.nongnu.org/cinvoke/)
• Io, tested with latest git (around October 2008)

CInvoke is licensed under the revised BSD license.

CInvoke for Io is only tested with the included samples; there is a minimal gtk example included.

There is no documentation at the moment, but it's planned.
