I think the error is trying to tell you the C reopen function takes a
pointer to a function and you are passing it a Go func. Try googling "cgo
pass function pointer". That should yield documents like

Hi,
You cannot pass f, which is a Go function, in a CGo call directly because
of the pointer passing rules. You need to create some wrappers, and I have

You are right Flush needs to write the header first, so the additional
header lines cannot be added by the server after Flush. The automatic
Content-Type might also not be written. A local proxy in front of your
server might be a simpler approach to measure full performance.

My reply was to Salih but somehow my reply ended up appearing first.
According to the purego docs you don't need a compiler, essentially it
provides a means of opening a dll/so and registering and calling functions
within the dll/so.

I know that there's purego https://github.com/ebitengine/purego but not
totally sure about it can preform without a compiler.

I would like to be able to access a dynamic C library (and ideally C++),
i.e., `.so` or `.dll` _without_ using cgo, i.e., without needing a compiler
on the target platform.
Python provides a `ctypes` module with this facility. Is there an
equivalent for Go?
