Default Problem holding, releasing, duplicate and destroy flowitems dynamically

Hi,

I have a separator which splits a flowitem into a static number. Most flowitems will exit this separator as normal, but not all. So I have a function which will destroy the uneeded flowitems, and then release one item which represents the rest. This must be dynamic, as I don't know how many items I will consume.

for example:
split flowitem to 10 elments
use 8
destroy 1
release 1 flowitem which represents the 2 not used

Since all splitted items are released, I do (holditem, destroyobject) on the flowitems to be destroyed, and (holditem, releaseitem) on the flowitem to be released, as it must exit through another port.

The problem is that if I try to split the flowitem released, flexsim generates an malloc error message.

What am I doing wrong?

code:

int num = content(current);
if (num > 0) {
treenode child = first(current);
while (content(current) > 1) {
holditem(last(current));
destroyobject(last(current));
}
setlabelnum(child, "quantity", num);
holditem(child);
releaseitem(child, getlabelnum(current, "return_port"));
}

Sebastian,

Why not release the unused flowitems into a combiner and combine them back together in zero time. You could set a label on the combiner or the flowitems so that the combiner could change the number of flowitems to combine on the fly. This way you don't have to write the excessive code and run into problems like the one you are having.

Brandon
