What did you do?
Looked in golang.org/x/sys/unix
for Renameatx_np
.
What did you expect to see?
Renameatx_np
.
What did you see instead?
Not Renameatx_np
. :)
The use case here is wanting to use RENAME_EXCL
.

Hi I am interested in this issue, but I kinda need more description for it. Does this issue mean I need to implement Renameatx_np
under darwin just like how we implement Renameat
?
Comment From: ianlancetaylor
Basically, yes. Although of course the argument types are different.

Change https://golang.org/cl/361958 mentions this issue: unix: implements RenamexNp and RenameatxNp for darwin

@elagergren-spideroak @HowJMay How about this implementation? (stil WIP) cc @ianlancetaylor
https://golang.org/cl/361958
I found sys package doesn't provide the copyfile.h
related functions.
Basically, it's Standard C Library copyfile(3)
, but Apple implements additional features which are APFS filesystem CoW clone. I also planning to implement those.

Hello,
What is the status of this issue? I found a need for the system call renamex_np with the RENAME_SWAP flag

The proposed change didn't get reviewed (which may have been my mistake) and it now has a merge conflict.
