Subject: fdstream: Raise explicit error when iohelper gets SIGPIPE
X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=c48db92fbd1776a46127c3e988a1650bfd5dcd53;p=libvirt.git

fdstream: Raise explicit error when iohelper gets SIGPIPE

This happens when virStreamFinish/Abort are called, but iohelper
still has data to process.
