I currently teach in Systems Programming Course for Year 2 Comp Sci students (24 lectures and 12 labs). For historical reasons I use C as the programming language. However in Year 1 the students learn Ada as their first language and it would seem more appropriate to use Ada for the course as it would free up time currently spent introducing the students to C and in particular into the joys of C arrays and pointers. Does anyone teach such a course and if so what packages do they recommend for POSIX compliant (and/or UNIX) systems calls? Are there any such good public-domain packages for use with gnat (on solaris)? We might also consider using commercial packages if the site-licensing fees were not too exhorbitant.
