Dear Ada colleague
I am interested in finding out more about ANY
Ada bindings for X-windows, Sunviews, SQL and UNIX system calls.
Are there any bublic domain software for those bindings ?
I would also like to hear about real usage experiences that
anyone on the net might have had with them.
Thanks in advance,
Mitsutaka Ito

Bindings for X-Windows, Sunview, and Unix are generally provided
by the compiler vendors. I believe the current issue of ACM SIGADA
Ada Letters had an article on the current state of the SQL binding
effort, which included five or so different proposed levels of
binding; that particular question has received considerable
attention over the last several years.
General efforts are underway to develop "secondary standards"
which would standardize various sorts of interfaces, such as
interfaces to manufacturer-provided (highly optimized) sort
routines, a standard file-system interface, etc. These are
tied in with the ongoing Ada 9X process.
As for experiences, I have found that the primary problem is
pinning down the precise semantics of the routines you're
interfacing to. If you have REAL documentation which fills
in the gaps not covered in the "official" documentation, then
the interfacing from Ada is fairly straightforward.
The only other problem is that Sunview, for example, is a moving
target. This causes problems in that the binding for the very
latest version of Sunview will be released months after you've
installed that very latest version. By the time the compiler
vendor upgrades the binding, yet another snazzy new version of
Sunview will probably have been released. However, you can
probably use the interface to C to implement it yourself if it's
really important to have those snazzy new features right away...
