When does this die?
}.delete (or smart pointer drop) occurs.| Issue | Design Question |
|---|---|
| Resource Leak | Did you manually open() without a wrapper class? |
| Use After Free | Did you capture a reference to a local variable in a lambda/thread? |
| Static Fiasco | Do statics depend on each other? (Use Meyers Singleton). |
Does it have a destructor?
Does it copy?
FILE* cannot copy. Delete copy constructor.| Pattern | Use Case |
|---|---|
| RAII Wrapper | FileHandle, LockGuard. |
| Scope Guard | std::scope_exit (Cleanup callback). |
| Rule of 5 | Copy/Move/Destructor implementation logic. |
