Subject: [musl] [patch] posix_fallocate.3: add note about error codes for musl.
Date: Sun, 13 Sep 2020 05:06:25 -0300	[thread overview]
Message-ID: <CAFDeuWPmWWHatxnZ9HsYN2fp3gagHOKCsKmVDj0F6us9XWKwFQ@mail.gmail.com> (raw)

As can be seen in

https://git.musl-libc.org/cgit/musl/tree/src/fcntl/posix_fallocate.c?id=73cc775bee53300c7cf759f37580220b18ac13d3

musl returns the syscall's errors directly, which means it doesn't
perform the same emulation as glibc, and, more relevant to this change,
it can return more errors than the ones currently listed in ERRORS.
