[edit] Requirements
For type L to be Lockable, it must meet the above condition as well as the following:
| Expression | Effects | Return value |
|---|---|---|
| m.try_lock() | Attempts to acquire the lock for the current execution agent (thread, process, task) without blocking. If an exception is thrown, no lock is obtained. | true if the lock was acquired, false otherwise |
[edit] Notes
The try_lock member functions obtains a non-shared lock on m on success.
[edit] Standard library
The following standard library types satisfy Lockable requirements:
| (C++11) |
provides basic mutual exclusion facility (class) |
| (C++11) |
provides mutual exclusion facility which can be locked recursively by the same thread (class) |
| (C++11) |
provides mutual exclusion facility which can be locked recursively by the same thread and implements locking with a timeout (class) |
| (C++17) |
provides shared mutual exclusion facility (class) |
| (C++14) |
provides shared mutual exclusion facility and implements locking with a timeout (class) |
| (C++11) |
provides mutual exclusion facility which implements locking with a timeout (class) |
