Re: How to make sure GC allocated resources stay around when used in C functions?

[Kagamin via Digitalmars-d-learn]

AFAIK, addRoot is for memory allocated in GC heap, and addRange 
is for other types of memory, so you can't add non-gc memory as 
root (just a guess, see docs). I would allocate whole Args in GC 
heap and add is as root, yes, it would prevent collection until 
the root is removed. A better way would be to store Args in a 
linked list in the widget, this way it will be fully managed, and 
Args will live as long as the widget class instance references 
them without additional tinkering with GC.
