No need to do the check yourself. If you're in pure-C code, just do: CFTypeRef obj = CFCreateType(…); // ... CFRelease(obj); In this case, you gain nothing by using CFMakeCollectable, as the variable obj will keep your object rooted until after the CFRelease anyway (as it will still exist on the stack or in a register). If you're in Obj-C code, just do: CFTypeRef obj = CFMakeCollectable(CFCreateType(…)); // no-op in non-gc; releases and makes eligible for collection in gc [(id)obj autorelease];//releases in non-gc only // ... Or: CFTypeRef obj = CFMakeCollectable(CFCreateType(…)); // no-op in non-gc; releases and makes eligible for collection in gc // ... [(id)obj release];//releases in non-gc only -- Clark S.
