Hi Terry, Hi Tomasz;
I am not an expert c++ programmer (in fact I have never before
programmed in a language that requires memory housekeeping), and it
is almost certainly the case that my plugins are causing the problem,
somehow. However, I have put extensive _TRACE commands in my AFL,
and I find that the error does not occur when my plugin is called.
It occurs during the execution of other AFL functions, although I
cannot find a consistent pattern to when the error occurs.
I REALLY appreciate the offer to send in my code -- that is SO
gracious -- and will do that in a case of last resort!
Meanwhile, two questions:
1. Is there a way to see the current available memory in real time,
or to have the _Trace command write it, from within AFL? This would
I think help me see what is causing the problem. Also, how much
total available memory is there to begin with? Sorry for being
stupid, but I just don't know.
2. What do I need to do regarding memory allocation in my plugins?
My plugin basically creates a set of AB string variables using
gSite.setvariable(),and it does this often. Can I assume that AB is
taking care of freeing this memory, or should I be calling gSite.free
() somewhere? I found this information on the board:
"You have to call gSite.Free for every array allocated in your code
via gSite.Alloc or gSite.GetArrayResult, and also for each and every
result returned by any built-in function called by CallFunction and
returned in AmiVar. The only exception is ONE array that you allocate
for the result and return in AmiVar variable as a result.
If you do not do this, the memory will be fred when formula finishes
its execution."
However, in my case I am not returning ONE array, but many string
variables. This seems a likely source of my problem, but I'm not
sure how to deal with it. Have I missed documentation on this issue?
Thanks for your time, I really appreciate it.
Chuck
