Calling convention isn't tricky at all. If AHCC is PureC compatible then all c function parameters are passed to m68k registers directly (there should be PureC doc file explaining that. I think that PureC archive from rg.atari.org will have it). So all data are passed to d0-d7 registers, pointers are slapped to a0-a6 (I think that's from left to right order, it isn't hard to figure it out with debugger). Floats are packed to fpu registers directly too (if it was enabled).
Everything that doesn't fit in registers goes on stack. If function will be declared with cdecl, then all parameters as far i remember goes on stack (,but this sucks).
I've made small PureC library for CT60(http://nokturnal.pl/home/atari/ct60lib), so there you can see how interfacing between C and m68k asm can be done. This is also done in GODLIB.

What's the anti-troll code?
That's your personal code to be able to add comments and messages on the dhs.nu site.
Don't have a code or forgot it? Fix it here.
