I can't speak to the Alsys binding, but the Apex binding (with which I have considerable experience) is conformant to IEEE Std 1003.5-1992, right down to the package names. Just like Ada compilers have some implementation details, the POSIX Ada binding also has some implementation lattitute. > > > One can get Florist with GNAT, but I'm not sure of the > > totality of support, especially when it comes to threads. > > I still haven't looked at Florist, but does it match Pascal > Obry's binding, as well as the Apex binding? Haven't done much with Florist. The anxiety I have is that it a POSIX binding doesn't come from the compiler vendor, then how is one to have confidence that the multi-tasking aspects of POSIX threads are compatible with Ada tasks and how are Text_IO Form parameters going to access POSIX access and file control fields (just to name two issues). > > Frank -- Samuel T.
