The SharedTimedLockable requirements describe the characteristics of types that provide timed shared blocking semantics for execution agents (threads, processes, tasks).
For type L to be SharedTimedLockable, given.
rel_time, a value of a specialization of std::chrono::duration, and abs_time, a value of a specialization of std::chrono::time_point, the following conditions have to be satisfied for an object m of type L:
| Expression | Requires | Return value |
|---|---|---|
m.try_lock_shared_for(rel_time) | Blocks for the provided duration rel_time or until a lock on m is acquired. |
true if the lock was acquired, false otherwise. |
m.try_lock_shared_until(abs_time) | Blocks until the provided time point abs_time is reached or a lock on m is acquired. |
true if the lock was acquired, false otherwise. |
The try_lock_shared_for and try_lock_shared_until member functions obtain a shared lock on m on succcess.
