Indeed, we lack that functionality in core Guile. > Am I mistaken, and are there any plans to add control message support to > Guile's library? I'm not aware of any plans to add it, but if we can agree on an API and someone contributed a suitable implementation, I don't see why we couldn't add it. In the meantime, it's easy to extend Guile with your own bits of C code. http://www.gnu.org/software/guile/manual/html_node/C-Extensions.html You could also probably use our Dynamic FFI to do the job entirely from Scheme, although we don't have any automatic way of dealing with C preprocessor macros, so they would probably have to be hard-coded. http://www.gnu.org/software/guile/manual/html_node/Foreign-Function-Interface.html Mark
