C++ named requirements: BasicLockable (since C++11)
The Lockable requirements extends the BasicLockable requirements to include attempted locking.
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 |
Notes
The try_lock member functions obtains a non-shared lock on m on succcess.
