-/* This file defines the following macros for accessing a small fixed
- set of thread-specific `void *' data used only internally by libc.
-
- __libc_tsd_define(CLASS, KEY) -- Define or declare a `void *' datum
- for KEY. CLASS can be `static' for
- keys used in only one source file,
- empty for global definitions, or
- `extern' for global declarations.
- __libc_tsd_address(KEY) -- Return the `void **' pointing to
- the current thread's datum for KEY.
- __libc_tsd_get(KEY) -- Return the `void *' datum for KEY.
- __libc_tsd_set(KEY, VALUE) -- Set the datum for KEY to VALUE.
-
- The set of available KEY's will usually be provided as an enum,
- and contains (at least):
- _LIBC_TSD_KEY_MALLOC
- _LIBC_TSD_KEY_DL_ERROR
- _LIBC_TSD_KEY_RPC_VARS
- All uses must be the literal _LIBC_TSD_* name in the __libc_tsd_* macros.
- Some implementations may not provide any enum at all and instead
- using string pasting in the macros. */

-#include <tls.h>
-
-/* When full support for __thread variables is available, this interface is
- just a trivial wrapper for it. Without TLS, this is the generic/stub
- implementation for wholly single-threaded systems.
-
- We don't define an enum for the possible key values, because the KEYs
- translate directly into variables by macro magic. */
