// For CF functions with 'Get' semantics, the compiler currently assumes that the result is autoreleased and must be retained. It does so on all platforms by emitting a call to objc_retainAutoreleasedReturnValue. On Darwin, this is implemented by the ObjC runtime. On Linux, there is no runtime, and therefore we have to stub it out here ourselves. The compiler will eventually call swift_release to balance the retain below. This is a workaround until the compiler no longer emits this callout on Linux.
void * objc_retainAutoreleasedReturnValue(void *obj) {
if (obj) {
swift_retain(obj);
return obj;
}
else return NULL;
