Hi! I am using an external library (LIB or DLL) to allocate and free memory that is not in the scope of the garbage collector, in the following example externalAlloc and externalFree. For better handling, I packed the memory pointer in a Julia struct. struct myStruct ptr function myStruct() …

[image] vettert: ?finalizer Ah yes, exactly what I was looking for! Thank you! (only thing is finalizer only works for mutable structs) To conclude my example, the solution would be: mutable struct myStruct ptr function myStruct() ptr = externalAlloc() inst = new(ptr) …

Is it possible to detect garbage collection on a custom struct?
