From 375a6294a41e003f873821a01d947f0ecfaf76d4 Mon Sep 17 00:00:00 2001 From: Thomas Graf Date: Tue, 2 Apr 2013 11:58:18 +0200 Subject: [PATCH] nl: Return -NLE_AGAIN if non-blocking socket would block Previously 0 was returned which gave the caller no chance of detecting when a non-blocking socket would block. If a caller intends to never see an error message it should utilize poll()/select() to only read when the socket has pending data or information.
