Your posted C code looks not too surprising for me, so I have no idea what the
problem may be.
Maybe you can try to investigate the cstring in more detail from inside your
Delphi code, for example its address, content of each character, terminating
NULL char.
Maybe the problem is just the GC,
Thanks you,
For some reason, it now works as expected, even without the packed pragma
(which I will use anyway). The code produced is the correct one. The only
difference on my systems (osx and linux) is that I changed from "brew install
nim" or "apt install nim" to choosenim for both.
Maybe..
I haven't used it but perhaps this help?

You just have to copy the constant values into Nim code. There is nothing
better I'm afraid.
Hi,
I need to replicate the idea of C bitfields.
struct iphdr {
__u8ihl:4,
version:4;
}
Run
but in Nim, the closest I got is:
IP_packet = object
version{.bitsize:4.}:uint8

Unless you expect exact result because all you are doing is copying, as soon as
computation is involved you need to check either the relative error or the
absolute error or both.

Go for it. But note that nativesockets is meant to be low-level, don't put too
much logic in there. The logic should go into `net` and `asyncnet`
Hi,
For "off the chart" networking programs, we need an empty service in Linux with
SOCK_RAW, otherwise, it keeps bothering with /etc/services, which we don't want.

I remember reading something a few years ago about the "this will eventually be
a compile-time error" thing being an inaccurate statement. If something like
that were added in the future, given Nim's direction, I would wager you could
probably get around it with a future compiler pragma.
AFAIK the `--noMain` doesn't mean "don't generate `NimMain()`". You still need
to `NimMain()` to boot the GC, execute top-level module code, etc.
I believe what the flag actually does is prevent `NimMain()` being called in
`DllMain()`, so you have to call `NimMain()` manually.
