From 323bee32e9bef14c6dd943ecc8e8cd373a9c94d9 Mon Sep 17 00:00:00 2001 From: Tom Tucker Date: Sun, 30 Dec 2007 21:07:31 -0600 Subject: svc: Add a transport function that checks for write space In order to avoid blocking a service thread, the receive side checks to see if there is sufficient write space to reply to the request. Each transport has a different mechanism for determining if there is enough write space to reply. The code that checked for write space was coupled with code that checked for CLOSE and CONN. These checks have been broken out into separate statements to make the code easier to read.
