I am porting my sockets interface from Windows NT to Red Hat Linux 5.1.
In 'C' FD_ZERO, FD_SET, FD_CLR, and FD_ISSET are implemented as macros in
the file /usr/include/selectbits.h
I would like to replicate their functionality in Ada, but am having a great
deal of difficulty in demangling the C code. Has anyone already implemented
these functions in Ada?
Note: I already looked at GNAT's System.Garlic.Thin which defines FD_SET but
does not define any of these operations.
Thanks in advance,
SteveD

It's not quite as simple as that. Several years ago, when I did my first sockets implementation in Ada (long before GNAT), I dutifully translated all the macros to Ada subprograms, and life was good until our UNIX vendor came out with a new version to which our customer insisted we migrate. Well, one thing in the C header files changed which rendered our Ada code incompatible, and it was difficult to find the cause of our large system's aberrant behavior. Then, we realized that the better course was to automatically generate C-functions implementing those macros, and interface Ada to those C functions, the approach which florist uses. In the florist sources, you will not find Ada implementations, but c-implementations to which the Ada code is interfaced. So.. I would recommend you just get and install florist. I haven't built the RedHat 5.1 florist981211.tar.gz (the current version), so I cannot comment specifically, but there are sure to be some things which will not work. Most of the time I found these were things in which I was not interested, or could see how to fix -- some with the kind help of Ted Baker and the folks at ACT (I had a support contract on that project). I would stay away from the 3.12w.fsu version, because it looks like it's for the fsu GNAT runtime. I have used florist (and its predecessor forest) for several years, now on several platforms, and have found it useful, in spite of its flaws. ^ permalink raw reply [flat|nested] 6+ messages in thread

Has anyone already implemented > these functions in Ada? The easiest way of doing this would perhaps be to write a C program that emitted an Ada module which containes the correct values for these and other constants. An alternative would perhaps be to use Perl instead of C. However I suspect that a C version will be easiest to handle. It should assure portability to other operating systems as the values would always be correct. Greetings, ^ permalink raw reply [flat|nested] 6+ messages in thread
