I may have given you a wrong lead. I am a C++ programmer and the AFL
syntax is much like it. I just use the C++ conventions and I have
not had any trouble, well not with syntax anyway. Hope I have not
misled you.
The unreliability may be caused by the sequence in which you declare
the "globals". If a function earlier in the code relies on a global
declared later that may cause the problem you have. A C++ compiler
would tell you but AFL does not and seems quite unforgiving at times.
I still think that passing parameters is the safest way to go. Or
declaring your globals at the beginning. Then you know for sure they
are global. If you declare them in functions you are just asking for
trouble and trouble seems to have found you so try some other way
and see if it helps.
Confusing huh? Learning AFL has been one confusing moment after
another for a couple of years now. I can't quite get the array based
mentality down pat and revert to procedural thinking and get all
screwed up. Thanks for trying to help me understand how AFL works, I
need all the help I can get.
Cheers,
Barry
