Subject: [PATCH] add function attributes to sprintf() and snprintf()
Date: Wed, 7 Nov 2001 17:24:01 +0100 [thread overview]
Message-ID: <20011107172401.I14594@arthur.ubicom.tudelft.nl> (raw)
Hi,
This patch adds function attributes to sprintf() and snprintf() so the
compiler can catch formatting errors at compile time. Patch is against
2.4.13-ac8, but it should apply cleanly against 2.4.14 as well.
Erik
