Subject: [PATCH 2/4] packet: Offset plus length is not always uint32_t, but it's always size_t
Date: Wed, 29 Nov 2023 14:46:08 +0100	[thread overview]
Message-ID: <20231129134610.3796809-3-sbrivio@redhat.com> (raw)
In-Reply-To: <20231129134610.3796809-1-sbrivio@redhat.com>

According to gcc, PRIu32 matches the type of the argument we're
printing here on both 64 and 32-bits architectures. According to
Clang, though, that's not the case, as the result of the sum is an
unsigned long on 64-bit.

Use the z modifier, given that we're summing uint32_t to size_t, and
the result is at most promoted to size_t.
