Do we actually need to use this function from the Globstruct when passing in strings from our plugin functions?

I wasn't asking how to use it. I was asking if we had to. Meaning... Is it safer to use to protect against memory leaks upon program termination.

There are no memory leaks at program termination - all memory allocated is automatically freed at that point.

During the program runtime however, you won't necessarily leak memory, but you could certainly corrupt the memory heap and cause a crash - memory you allocate in your DLL can be freed by the DBPro runtime, and memory the DBPro runtime allocates can be freed by your DLL. This mixing of memory from different heaps is a no-no.

Bottom line: You should use the function provided. That's why it's provided.

That makes sense. Thanks for clearing that up for me.
