[Mono-list] Interop

[William S Fulton]

SWIG has automated support for calling unmanaged code from managed code. 
Currently there is no automated support for wrapping C function pointers 
and making callbacks to managed code using delegates. However, if you 
have a large library you want to wrap, you can provide code manually to 
do this using SWIG typemaps and features. This can be a bit fiddly to 
set up but if you have lots of code to wrap SWIG is very powerful.
