julia> foo() = Cint(1) foo (generic function with 1 method) julia> ptr = cfunction(foo, Cint, Tuple{}) Ptr{Nothing} @0x00007f5dacc48510 Is it possible to derive foo from ptr?

No you can’t do that. Only with debug info maybe but that shouldn’t be used in normal code. [image] mohamed82008: unsafe_wrap(Array, reinterpret(Ptr{typeof(foo)}, ptr), (), false); This is only a complicated way to spell typeof(foo).instance. The ptr is not used AT ALL.

unsafe_wrap(Array, reinterpret(Ptr{typeof(foo)}, ptr), (), false)[] uses foo, and I’m curious if it can be done without it. Sorry if I was unclear.
