Is there any docs about it? I don't find the cygwin.cygport file in source
tree. Also I don't use source tarballs, git is my first choice. Also the
configure script
Now I'm sure that the issue in cygwin source code. I've installed all the
components. Also find same issue[1] provided a year ago. Cygwin needs some
papering[2] for gcc 8.3.0.

Can anyone provide a function calls between cygwin socket() and Windows
socket() as a flowchart? For example, with AF_INET.
In source code (fhandler_socket_inet::socket), I see bunch of function
pointers which seems confusing to me.

FAQ:
If a function calls both cygwin and Windows functions the binary creates
extra subroutine (in assembly) for cygwin ones. Example:
* Windows function:
call cs:CreatePipe
* cygwin function:
call ioctl
ioctl proc near
jmp cs:__imp_ioctl
endp
The binary is statically compiled. Why
I've tried to use poll() with a Windows socket (from WSASocket) and a
cygwin side file descriptor (fd). But it is only signaled for fd only.
At first, I have seen that fhandler_socket_wsock::set_socket_handle() casts
SOCKET to int. So, is it possible to use poll() with the SOCKET type? Or Is

The HPCON isn't a handle. It's a pointer of a struct of three handles. In
my opinion, I think it's consistent with pty functions in libc. Like in

It seems to be issue in Travis CI. See this forum post:
https://travis-ci.community/t/cygwin-issue-cygheap-base-mismatch-detected/5359
If you are in hurry you can use Appveyor CI. I'm using it without any
issue. One has to just add `C:\cygwin64\bin` in PATH variable in YAML file.

I want to use socket() from ws2_32.dll file. But cygwin1.dll also has that
export. When I use `-lws2_32` option, will gcc **always** choose
ws2_32.lib? My query is somewhat similar with FAQ #5.11.

The C header files are way behind the current mingw-w64 repository. Can you
update that package in cygwin?

I did not mean the release page [1]. I mean the cygwin headers is older
than the current mingw-w64 git repository [2]. The latest tag is v6.0.0.
[3]
Wait, did you mean there should be a new "stable" tag or release in
mingw-w64 so that cygwin can import it?

Also, w32api-headers version 7 for x86_64 is missing.

Same issue here. I use git in msys2 for correct file permissions. Also
if I install cygwin and reinstall Windows 10 OS then Windows programs
can not edit any cygwin files. I have to take ownership with takeown
and icacls commands then chmod the files.
I found a temporary workaround. 1. Add `noacl`

Chaging the defines in package may break others installation. You can set
the version in source code as you need, for example:
#undef _WIN32_WINNT
