/* 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. */
