Sorry, what? This method only [returns process ID](https://ruby-doc.org/core-3.0.1/Process.html#method-c-pid), what do you mean about "send signals to `Process.pid`"? xtkoba (Tee KOBAYASHI) wrote in #note-4: > I suppose it is not easy to make POSIX signals consistent with Windows. Either the list of signals should be shortened and consistent among methods (`Process.kill`, `Signal.list`, `Signal.trap`, etc.), or some of these methods should raise an exception, like `Process.getpgid`: `getpgid() function is unimplemented on this machine (NotImplementedError)`. ---------------------------------------- Bug #17820: `Errno::EINVAL` from `Process.kill` with available signal on Windows https://bugs.ruby-lang.org/issues/17820#change-91666 * Author: AlexWayfer (Alexander Popov) * Status: Open * Priority: Normal * ruby -v: ruby 3.0.1p64 (2021-04-05 revision 0fb782ee38) [x64-mingw32] * Backport: 2.6: UNKNOWN, 2.7: UNKNOWN, 3.0: UNKNOWN ---------------------------------------- Hello. I've installed Ruby on Windows via [Chocolatey](https://community.chocolatey.org/packages/ruby). I receive `Errno::EINVAL` from `Process.kill` with almost every signal. Only `0` seems working. `TERM` (`15`), `INT` (`2`) ��� don't. Although they're in `Signal.list` output: ![](clipboard-202104222051-b64xq.png) ---Files-------------------------------- clipboard-202104222051-b64xq.png (63.9 KB) clipboard-202104222318-tbufr.png (96.8 KB) -- https://bugs.ruby-lang.org/ Unsubscribe:
