thread-local storage

Each thread has its own copy of the thread-local storage table.

One of the entries in this block is the thread-local storage table for that thread.

The thread-local storage is created under the variable's key, and the new value is stored there.

If each thread binds some special variable , then behaves like thread-local storage.

Current Linux also uses GS to point to thread-local storage.

In Python version 2.4 or later, local class in threading module can be used to create thread-local storage.

Fiber-local storage, analogous to thread-local storage, may be used to create unique copies of variables.

Kernel threads do not own resources except for a stack, a copy of the registers including the program counter, and thread-local storage (if any).

Thread-local storage (TLS) is a computer programming method that uses static or global memory local to a thread.

A new thread-local storage duration (in addition to the existing static, dynamic and automatic) is indicated by the storage specifier .

In Object Pascal (Delphi) or Free Pascal the threadvar reserved keyword can be used instead of 'var' to declare variables using the thread-local storage.

This includes dynamic library references for linking, API export and import tables, resource management data and thread-local storage (TLS) data.

The programming model is based on a single thread of execution and use of them by multiple threads has to be handled by a means outside of the standard (e.g. C11 specifies that the flags have thread-local storage).

Microsoft Visual Basic substantially enhanced the HRESULT error reporting mechanisms, by associating an object with an HRESULT error code, by storing a pointer to an IErrorInfo COM object in thread-local storage.
