/* 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, TYPE, KEY) -- Define or declare a datum with TYPE
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(TYPE, KEY) -- Return the `TYPE *' pointing to
the current thread's datum for KEY.
__libc_tsd_get(TYPE, KEY) -- Return the `TYPE' datum for KEY.
__libc_tsd_set(TYPE, 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. */

/* 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. */
