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)

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?
