Subject: internal / external include files
Date: Wed, 24 Jul 2019 11:11:00 +0200	[thread overview]
Message-ID: <20190724091100.lcfw3y7nbcelvgrc@viti.kaiser.cx> (raw)

Dear all,

is it correct that the files under include/uapi/ can be included by a
user space application?

I just ran into an error where my application ended up including
include/uapi/linux/stddef.h (with a number of intermediate steps).

This fails because the kernel's stddef.h includes
include/linux/compiler_types.h and this file is internal to
the kernel.

What is the correct way to solve this? Should I fix my include path to
make sure that my application picks the stddef.h in the compiler's
sysroot rather than the kernel's stddef.h?

Or should include/uapi/linux/stddef.h guard the kernel-internal parts
using #ifdef __KERNEL__?

Thanks,
Martin
