Subject: [PATCH 07/22] lio_listio.3: SYNOPSIS: Use 'restrict' in prototypes
Date: Sat,  6 Mar 2021 00:50:51 +0100	[thread overview]
Message-ID: <20210305235105.177359-8-alx.manpages@gmail.com> (raw)
In-Reply-To: <20210305235105.177359-1-alx.manpages@gmail.com>

Both POSIX and glibc use 'restrict' in lio_listio().
However, POSIX is a bit more restrictive than glibc
for the second parameter.
Let's document the more restrictive POSIX variant.

$ man 3p lio_listio |sed -n '/^SYNOPSIS/,/;/p'
SYNOPSIS
       #include <aio.h>

       int lio_listio(int mode, struct aiocb *restrict const list[restrict],
           int nent, struct sigevent *restrict sig);
$

.../glibc$ grep_glibc_prototype lio_listio
rt/aio.h:148:
extern int lio_listio (int __mode,
		       struct aiocb *const __list[__restrict_arr],
		       int __nent, struct sigevent *__restrict __sig)
  __THROW __nonnull ((2));
.../glibc$
