Issue #4512 has been updated by Motohiro KOSAKI.


I'm waiting the discussion of #5041.
----------------------------------------
Feature #4512: [PATCH] ext/fcntl/fcntl.c: add F_DUPFD_CLOEXEC constant
http://redmine.ruby-lang.org/issues/4512

Author: Eric Wong
Status: Assigned
Priority: Normal
Assignee: Motohiro KOSAKI
Category: ext
Target version: 1.9.x


=begin
It's in POSIX.1-2008 and will be useful when Ruby becomes more
multi-threaded.

related: http://redmine.ruby-lang.org/issues/1291

If/when 1291 goes through I'd also like IO#dup to work with the dup3()
system call, but this patch is much less intrusive.
