Subject: Re: AF_UNIX MSG_PEEK bug?
Date: Tue, 08 Jan 2008 14:40:22 -0800	[thread overview]
Message-ID: <4783FBD6.1000004@hp.com> (raw)
In-Reply-To: <alpine.BSF.1.00.0801081556580.24286@pkunk.americas.sgi.com>

Potential bugs notwithstanding, given that this is a STREAM socket, and 
as such shouldn't (I hope, or I'm eating toes for dinner again) have 
side effects like tossing the rest of a datagram, why are you using 
MSG_PEEK?  Why not simply read the N bytes of the message that will have 
the message length with a normal read/recv, and then read that many 
bytes in the next call?
