condition_variable_any();	(1)	(since C++11)
condition_variable_any( const condition_variable_any& ) = delete;	(2)	(since C++11)

1) Constructs an object of type std::condition_variable_any.

2) Copy constructor is deleted.

Parameters

(none)

Exceptions

1) May throw std::system_error with std::error_condition equal to std::errc::operation_not_permitted if the thread has no privilege to create a condition variable, std::errc::resource_unavailable_try_again if a non-memory resource limitation prevents this initialization, or another implementation-defined value.

Defect reports

The following behavior-changing defect reports were applied retroactively to previously published C++ standards.

DR	Applied to	Behavior as published	Correct behavior
LWG 2092	C++11	the error condition for resource_unavailable_try_again was wrong	corrected
