This API really sucks; it literally just passes through the raw SMB request. However, there are some benefits over FSCTL_DUPLICATE_EXTENTS_TO_FILE:
1. it's easier to use from setupapi than FSCTL_DUPLICATE_EXTENTS_TO_FILE which can't plausibly be emulated. 2. on Windows, IOCTL_COPYCHUNK is already called (indirectly) from CopyFile on Windows. see e.g. https://www.ghisler.ch/board/viewtopic.php?t=43945. 3. copy_file_range allows kernel acceleration. 4. copy_file_range is supported on FreeBSD. --- configure | 1 + configure.ac | 1 + dlls/ntdll/unix/file.c | 121 +++++++++++++++++++++++++++++++++++++++++ include/config.h.in | 3 + include/winioctl.h | 34 ++++++++++++ 5 files changed, 160 insertions(+)
