Subject: Re: [PATCH 1/2] git_mkstemps: correctly test return value of open()
Date: Thu, 18 Jul 2013 08:32:30 -0400	[thread overview]
Message-ID: <51E7E05E.4000201@gmail.com> (raw)
In-Reply-To: <7v38rd6l3j.fsf@alter.siamese.dyndns.org>

I presume that I should apply this change to my porting of 
git_mkstemps_mode() to tig. If there are no complaints about this for a 
couple of days I will do so.
