Subject: [PATCH 08/12] get_oid_hex_segment(): return 0 on success
Date: Sat, 26 Aug 2017 10:28:08 +0200 [thread overview]
Message-ID: <1a421226c8f7cb3cb7609cb4bd06ed009430a543.1503734566.git.mhagger@alum.mit.edu> (raw)
In-Reply-To: <cover.1503734566.git.mhagger@alum.mit.edu>
Nobody cares about the return value of get_oid_hex_segment() except to
check whether it failed. So just return 0 on success.
And while we're updating its docstring, update it for some argument
renaming that happened a while ago.
