OS X 10.10 (IOS 8.0) add list of *at syscalls.

  • openat
  • renameat
  • fchmodat
  • fstatat
  • mkdirat
  • faccessat
  • fchownat
  • linkat
  • readlinkat
  • symlinkat
  • unlinkat

Currently, only fchmodat is exposed.

These syscalls are also supported on FreeBSD, and I need them for a project that currently only supports Linux.

I would like to second both requests (darwin / FreeBSD) in this issue.
Other popular BSDs (Net, Open)most likely support the requested system calls as well.

Yes. Openat is required, as I understand it, to be able to reliably open a path without following symlinks. Currently this is only possible on Linux, with Go...
