C++ named requirements: BasicLockable (since C++11)

The BasicLockable requirements describe the minimal characteristics of types that provide exclusive blocking semantics for execution agents (i.e. threads).


For type L to be BasicLockable, the following conditions have to be satisfied for an object m of type L:

Expression Preconditions Effects
m.lock() Blocks until a lock can be acquired for the current execution agent (thread, process, task). If an exception is thrown, no lock is acquired.
m.unlock() The current execution agent holds a non-shared lock on m. Releases the non-shared lock held by the execution agent.

Throws no exceptions.

Non-shared locks

A lock on an object is said to be non-shared lock if it is acquired by a call to lock, try_lock, try_lock_for, or try_lock_until member function.
