Documentation:

• man copy_file_range.

Gnulib module: copy-file-range

Portability problems fixed by Gnulib:

• This function exists only on Linux and FreeBSD and is therefore missing on many platforms: glibc 2.26, macOS 14, FreeBSD 12.0, NetBSD 10.0, OpenBSD 6.7, Minix 3.1.8, AIX 7.1, HP-UX 11.31, Solaris 11.4, Cygwin 2.9, mingw, MSVC 14, Android API level 33. But the replacement function is only a stub: It always fails with error ENOSYS.
• This function has many problems on Linux kernel versions before 5.3. On these kernel versions, the replacement function always fails with error ENOSYS.
