Subject: [PATCH 12/14] tools/top: The string parameter in set_prompt() and set_delay() should be const
Date: Mon,  5 Apr 2021 16:57:11 +0100	[thread overview]
Message-ID: <20210405155713.29754-13-julien@xen.org> (raw)
In-Reply-To: <20210405155713.29754-1-julien@xen.org>

From: Julien Grall <jgrall@amazon.com>

Neither string parameter in set_prompt() and set_delay() are meant to
be modified. In particular, new_prompt can point to a literal string.

So mark the two parameters as const and propagate it.
