      thread_local

      From cppreference.com
      <c‎ |thread
       
       
      Concurrency support library
       
      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 hasthread-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.
