WebFeb 14, 2024 · Thread-local storage (TLS) provides a mechanism allocating distinct objects for different threads. It is the usual implementation for GCC extension __thread, C11 _Thread_local, and C++11 thread_local, which allow the use of the declared name to refer to the entity associated with the current thread. WebTLS sections are managed using memory pagingand its size is quantized to a page size (4kB on x86 machines). Such sections may only be defined inside a main executable of a program - DLLsshould not contain such sections, because they are not correctly initialized when loading with LoadLibrary.
