Thread-local storage
Defined in header
<threads.h>
#define thread_local _Thread_local
(since C11) (removed in C23)
Convenience macro which can be used to specify that an object has thread-local storage duration.
[edit] Notes
Since C23, thread_local is itself a keyword, which may also be a predefined macro, so <threads.h> no longer provides it.
