std::condit...variable_any(3)

💖 NAME 💖

std::condition_variable_any::condition_variable_any — this is the constructor page for std::condition_variable_any, bestie. The original NAME line is literally std::condition_variable_any::condition_variable_any - std::condition_variable_any::condition_variable_any, and we are keeping that exact energy. It lives in the C++ Standard Library manual as std::condit...variable_any(3). ✨

🌸 Synopsis 🌸

Two constructor situations, both since C++11, no cap:

          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) — literally no parameters, not even a tiny one. 🫶

💅 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.

heads up bestie: constructor (1) can throw, so do not act surprised if your thread lacks privileges or the system hits some non-memory resource limit. 😭

🫶 Defect reports 🫶

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

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