Why would you want to do that? IMHO, the code in /usr/src/sbin/devd/devd.cc is beautiful, concise and very readable. > Is it useful for something, or have I been wasting my time for nothing? What's the size of your C version of /sbin/devd? The statically linked C++ version is 402080 bytes on my amd64 system: % ls -l `which devd` -r-xr-xr-x 1 root wheel 402080 May 4 10:24 /sbin/devd and it will probably be less if written in C. That's the only advantage I see in translating C++ code to C code. For everything that's dynamically linked, I don't really see the point (with the exception of very few special cases). -cpghost. -- Cordula's Web. http://www.cordula.ws/
