- Recursive: The mutex can be locked multiple times by the same thread, for example, in a recursive function.
- Shared: The mutex can be locked in shared mode by multiple threads, for example, for reading.
| Mutex | Timed | Recursive | Shared |
|---|---|---|---|
std::mutex | ❌ | ❌ | ❌ |
std::timed_mutex | ✅ | ❌ | ❌ |
std::recursive_mutex | ❌ | ✅ | ❌ |
std::recursive_timed_mutex | ✅ | ✅ | ❌ |
std::shared_mutex | ❌ | ❌ | ✅ |
