Subject: [RFC PATCH v1 04/12] device-mapper: Replace strstarts() by str_has_prefix().
Date: Fri,  4 Dec 2020 18:03:10 +0100	[thread overview]
Message-ID: <20201204170319.20383-5-laniel_francis@privacyrequired.com> (raw)
In-Reply-To: <20201204170319.20383-1-laniel_francis@privacyrequired.com>

From: Francis Laniel <laniel_francis@privacyrequired.com>

The two functions indicates if a string begins with a given prefix.
The only difference is that strstarts() returns a bool while str_has_prefix()
returns the length of the prefix if the string begins with it or 0 otherwise.
