Subject: [PATCH] 2.4.20: lib/vsprintf.c: Fix vsscanf of hex digits
Date: Wed, 5 Mar 2003 09:31:23 -0600 [thread overview]
Message-ID: <0303050931230P.05199@boiler> (raw)
Hi,
The current vsscanf() in 2.4 does not correctly scan hex digits that begin
with a-f. (It does work correctly for hex digits that begin with 0-9). This
patch fixes that bug, and is based on the fix that was added to 2.5.
