Last change on this file since 73172 was 69720, checked in by vboxsync, 7 years ago

IPRT: More work on directory relative APIs (NT mainly) and VFS; introducing RTRmDir (test) tool.

  • Added RTVfsDirRemoveDir
  • Native NT implementation of RTDirRelRemoveDir.
  • Improved the RTFS_TYPE_DIRECTORY case of rtVfsStdDir_UnlinkEntry.
  • Added two new status code conversions to RTErrConvertFromNtStatus.
  • Property svn:eol-style set to native
  • Property svn:keywords set to Author Date Id Revision
