Move to Ready.

Proposed resolution:

Change Mutex requirements 33.6.4 [thread.mutex.requirements], paragraph 4, as indicated:

Error conditions:

Change Class condition_variable 33.7.4 [thread.condition.condvar], default constructor, as indicated:


Effects: Constructs an object of type condition_variable.

Throws: std::system_error when an exception is required (33.2.2 [thread.req.exception]).

Error conditions:

  • not_enough_memory — if a memory limitation prevents initialization.
  • resource_unavailable_try_again — if some non-memory resource limitation prevents initialization.
  • device_or_resource_busy — if attempting to initialize a previously-initialized but as of yet undestroyed condition_variable.
