Hi Rishi
The rebol part of accessing a shared library (dll in Windows) is illustrated
by a script on the Ecotope rebsite. The script shows how to access the
functions in the C-Runtime library crtdll.dll on Win98. Just change the
extension to .r.
http://www.nwlink.com/~ecotope1/reb/clib.txt
If you want to access some custom functions written in C, you will have to
get a C programmer to write the code and compile it to a dll which exports
those functions. They will be able to tell you the args and return specs for
wrapping it in a Rebol routine. You need a View/Pro license or Command to
access a shared library.
