AmigLoadable File Format
8 messages in this thread
I've got a question for the Amiga Guru's out there. The Amigados
Technical Reference Manual describes the file format for loadable binary
files. What I'm not sure I understand are the references to "Resident
Libraries." The manual makes it sound like these are not the same as the
shared libraries in libs. Is this something that was planned for future
expansion, but never happened, or what?
The reason I askis because I've been toying with the idea of writing
something like PowerPacker, with a few new features. Data Compression is
easy, as I can beat ZIP's implosion. Interpreting the expanded chunks is
what I think will give me problems.

P.S. One of the new features is an option for the decompression to be done
by a shared library routine, so that should get rid of about 400 bytes of
overhead As compared to PowerPacker (as I don't know how large my dedicated
extraction routine will be yet).
P.P.S Also in the works is a CLI based zip file creator, extractor, and a
self-extracting archive creator.
Argh! Yet another programmer worried about "400 bytes overhead"!
John, but those 400 bytes can be gotten rid of by haveing a 2K library
loaded.

And what about the number of bytes taken up by glue code, too?
If you are using SAS/C, the code for calling directly is smaller than the
code for calling the stub – plus you lose the stub to boot.
You do realize that Vic and I were joking around, don't you? Ah, but a plug
is a plug. 🙂 Nice to see you around here lately…
Actually, I can't figure out how to get the original messages yet – gee,
wouldn't a reliable Whap be nice 🙂 🙂 :-). I'm trying hard to keep up
to speed here while other things are being done… Sorry if I got the wrong
impression from the messages, one day I'll understand how to navigate.
John! Glad to see you over here, never thought I'd see you anywhere but
the… other net you frequent. A sign that the level of technical expertise
over… here is going up in general, I'm sure (hey, I can suck-up as good
as anybody… 🙂 –Eet–
