Issue #9323 has been updated by ioquatix (Samuel Williams).


I think this is a great idea. It avoids a ton of string issues - e.g. concatenating strings in Ruby before writing them out. It would be great if #write could take an array, and if possible, call writev.

Feature #9323: IO#writev
https://bugs.ruby-lang.org/issues/9323#change-65269

* Author: Glass_saga (Masaki Matsushita)
* Status: Open
* Priority: Normal
* Assignee: 
* Target version: 2.2.0
----------------------------------------
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.
