# HG changeset patch # User john.levon(a)sun.com # Date 1233118371 28800 # Node ID f91041f0c607be72c4b5695f081d20716521f6c5 # Parent 8fce2ce6108eb1ff1865ecc21d57114db036f2a2 Fixes for VNC port handling When parsing sexpr, the VNC port should not be ignored, even when vncunused is set. Fix the parsing of vncdisplay, which was broken due to strtol() (never use this function!).
