I tend to favor this approach too. The resident components are better written in ASM for speed and reduced memory footprint while the userland is better written in C for ease of development and code-sharing between components. > C is OK.

C is just at the right point between high level and low to be most useful for these things. -uso. ------------------------------------------------------------------------------ One dashboard for servers and applications across Physical-Virtual-Cloud Widest out-of-the-box monitoring support with 50+ applications Performance metrics, stats and reports that give you Actionable Insights Deep dive visibility with transaction tracing using APM Insight. http://ad.doubleclick.net/ddm/clk/290420510;117567292;y _______________________________________________ Freedos-devel mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/freedos-devel
