Well, here's the problem. I rewrote armlets/search.c to call a search
routine that is used for both 68K 8bit search and ARM 8bit
search. Anyway, I first tried:
Char DoSearch8Bits( args )
{
...;
}
UInt32 NativeFunction( args )
{
...;
DoSearch8Bits();
...;
}
This failed (it was a graceful failure, in that there was no hang, but it
found nothing). I haven't tested whether it was actually entering
DoSearch8Bits(), but my suspicion is that it was using it as the entry
point. On the other hand, if I reversed the order of the functions in my
source file (putting a declaration of DoSearch8Bits() first, of course),
it worked fine.
I remember when I was making my search armlet in the first place, I had
similar problems.
