Suppose we have the following structs matching some structs in a C header: struct Foo a::UInt32 b::Cstring end struct Bar a::UInt32 b::Ptr{Foo} end And we have a function that takes a ptr to Bar. ccall will handle one conversion (from Bar to a Bar pointer) for us, and writing a fu…

[image] cshenton: What’s the idiomatic way to create a pointer to a Foo , since pointer_from_objref should not be called on immutables? fooref = Ref(foo_object) GC.@preserve fooref begin ptr = Base.unsafe_convert(Ptr{Foo}, fooref) ....some code using ptr.... end Here, I used GC.@pre…
