This function exists only on Linux and is therefore
missing on older glibc versions and many non-glibc platforms:
glibc 2.9, macOS 11.1, FreeBSD 13.0, NetBSD 9.0, OpenBSD 6.7, Minix 3.1.8, AIX 5.1, HP-UX 11, IRIX 6.5, Solaris 11.4, Cygwin 2.9, mingw, MSVC 14, Android 4.4.

On platforms where @code{off_t} is a 32-bit type, this function may not
