Re: [libvirt] [PATCH 04/13] Add a generic reference counted virObject type

From: "Daniel P. Berrange" <berrange(a)redhat.com&gt; This introduces a fairly basic reference counted virObject type and an associated virClass type, that use atomic operations for ref counting. +void *virObjectNew(virClassPtr klass) +{ + virObjectPtr obj = NULL; + char *somebytes; + + if (VIR_ALLOC_N(somebytes, klass->objectSize) < 0) { + virReportOOMError(); + return NULL; + } + obj = (void*)somebytes; + + obj->magic = klass->magic; + obj->klass = klass; + virAtomicIntSet(&obj->refs, 1);
