Lockable
Lockable type (mutex type)
- BasicLockable
- Lockable
- TimedLockable
A lockable type (also known as mutex type) is a BasicLockable type that supports try_lock.
Types
The standard library defines the following Lockable types:| header | type |
|---|---|
| <mutex> | mutex |
| recursive_mutex | |
| timed_mutex | |
| recursive_timed_mutex |
Requirements
A value m is of a Lockable type if the following expressions are well-formed:- m.lock()
- Effects: Block until a lock can be acquired for the current execution agent. If an exception is thrown, then a lock shall not have been acquired for the current execution agent.
- m.unlock()
- Requires: The current execution agent shall hold a lock on m.
- Effects: Releases a lock on m held by the current execution agent.
- Throws: Nothing.
- m.try_lock()
- Effects: Attempts to acquire a lock for the current execution agent without blocking. If an exception is thrown, then a lock shall not have been acquired for the current execution agent.
- Return type:
bool - Returns:
trueif the lock was acquired,falseotherwise.
