Subject: [ruby-core:82020] [Ruby trunk Feature#9323] IO#writev

Issue #9323 has been updated by Glass_saga (Masaki Matsushita).


> It would be great if #write could take an array, and if possible, call writev.

That's would be nice.

```
File.open("test", "w") do |f|
  f.write("foo", "bar", "baz") # use writev(2) if possible
end
```

----------------------------------------
Feature #9323: IO#writev
https://bugs.ruby-lang.org/issues/9323#change-65749

* Author: Glass_saga (Masaki Matsushita)
* Status: Open
* Priority: Normal
* Assignee: 
* Target version: 2.5
----------------------------------------
I propose addition of IO#writev.
It enables gather output from multiple buffers.
If writev(2) is not available, IO#writev uses Array#join to emulate atomic write.
