From 45619dc71e9411a526d7c69595cf615b1b1206cf Mon Sep 17 00:00:00 2001 From: Daniel Martin Date: Sat, 8 Jun 2013 11:20:39 +0200 Subject: [PATCH] c_client.py: Inject full_sequence into GE events The generic event structure xcb_ge_event_t has the full_sequence field at the 32byte boundary. That's why we've to inject this field into GE events while generating the structure for them. Otherwise we would read garbage (the internal full_sequence) when accessing normal event fields there.
