Subject: [PATCH v2 05/13] tools/nolibc: add more wait status related types
Date: Tue, 30 May 2023 03:51:48 +0800	[thread overview]
Message-ID: <e578baa7116bb09f406a2beaea8298f7bbb22d6c.1685387484.git.falcon@tinylab.org> (raw)
In-Reply-To: <cover.1685387484.git.falcon@tinylab.org>

More wait status related types are added for the coming waitid syscall
based wait4() support.

Resue the ones from <linux/wait.h>, add the missing ones from sys/wait.h
and bits/waitstatus.h of glibc.
