We discussed it. It was a typo in the manual page. There never was a <sys/memfd.h> header file:
https://marc.info/?l=linux-man&m=150988359906012&w=2 The UAPI header is called <linux/memfd.h>.The downside of using a separate header is that you cannot determine, using the preprocessor alone, whether the toolchain provides the memfd_create function. If we put everything in <sys/mman.h>, you can use “#ifdef MFD_CLOEXEC” to see if the definitions and declarations are there.
Thanks, Florian
