From 89b48b56812a1a2d5b7edc927a7853d952e7fb38 Mon Sep 17 00:00:00 2001 From: Paolo Bonzini Date: Sat, 12 Mar 2011 17:43:54 +0100 Subject: add assertions on the owner of a QemuMutex These are already present in the Win32 implementation, add them to the pthread wrappers as well. Use PTHREAD_MUTEX_ERRORCHECK for mutex operations. Later we'll add tracking of the owner for cond_signal/broadcast.
