In computer programming, thread-local storage (TLS) is a memory management method that uses static or global memory local to a thread. The concept allows storage of data that appears to be global in a system with separate threads.
Thread-local storage Variables are localized so that each thread has its own private copy. These variables retain their values across subroutine and other code boundaries and are thread-safe since they are local to each thread, even though the code which accesses them might be executed simultaneously by another thread. Immutable objects
The Thread Information Block (TIB) or Thread Environment Block (TEB) is a data structure in Win32 on x86 that stores information about the currently running thread. It descended from, and is backward-compatible on 32-bit systems with, a similar structure in OS/2. [1] The TIB is officially undocumented for Windows 9x.
It is also possible in Windows Vista to specify a limit for the total size of the local cache and another sub-limit for the space used by automatically cached files. Manually cached files are never removed from the local cache even if the cache limit is reached. In Windows XP, Offline Files could not be enabled when Fast User Switching was ...
A new thread-local storage duration (in addition to the existing static, dynamic and automatic) is indicated by the storage specifier thread_local. Any object which could have static storage duration (i.e., lifetime spanning the entire execution of the program) may be given thread-local duration instead.
The stack is often used to store variables of fixed length local to the currently active functions. Programmers may further choose to explicitly use the stack to store local data of variable length. If a region of memory lies on the thread's stack, that memory is said to have been allocated on the stack, i.e. stack-based memory allocation (SBMA).
If you've received a notification that a limit has been met, you'll need to wait a set amount of time before you can send more emails. Most sending limit notifications inform you of how long you'll have to wait. If you're planning to regularly send bulk email, consider looking into alternate solution.
On Microsoft Windows, fibers are created using the ConvertThreadToFiber and CreateFiber calls; a fiber that is currently suspended may be resumed in any thread. Fiber-local storage, analogous to thread-local storage, may be used to create unique copies of variables. [3] Symbian OS used a similar concept to fibers in its Active Scheduler.
