Description

This is hrev53917.

Currently there are no ability to retrieve path of file descriptor. _kern_entry_ref_to_path(dev, node, NULL, path, B_OS_NAME_LENGTH) is only work for directories.

All major OS are support this feature:

  • Windows: GetFileInformationByHandleEx with FileNameInfo.
  • Linux: Path can be retrieved from /proc/self/fd/<fd>.
  • Mac OS X: fcntl(fd, F_GETPATH, filePath).
