	P3699R1	Rename `conqueue_errc`	Detlef Vollmann D. Vollmann	LEWG	2025-06-17	2025-07
Doc Date 2025-06-17 Mailing Date 2025-07 Post-Sofia Author(s) Detlef Vollmann Target Audience LEWG Tracking issue View on GitHub Abstract The proposal for concurrent queues [C++ Concurrent Queues (P0260)](https://wg21.link/P0260) uses an enumeration to specify possible return states of some queue operations. This enumeration is called `conqueue_errc` as it was originally meant for exceptions. However, the concurrent queue proposal doesn’t propose it’s own exception class anymore, so the name is misleading.
