Variable declarations removed. (__ctype_b_loc, __ctype_toupper_loc, __ctype_tolower_loc): Declare these functions to replace them. (__isctype, tolower, toupper, _tolower, _toupper): Use those accessor functions plus an indirection rather than the old global variables. * include/ctype.h (__isctype, tolower, _tolower, toupper, _toupper): Macros removed. (__ctype_b_loc, __ctype_toupper_loc, __ctype_tolower_loc): New extern inline functions. * ctype/ctype-info.c: Revert last reversion back the other way. Define tsd vars CTYPE_B, CTYPE_TOLOWER, CTYPE_TOUPPER. Define real function versions of include/ctype.h inlines here. * ctype/Versions (libc: GLIBC_2.3): Add __ctype_b_loc, __ctype_tolower_loc, __ctype_toupper_loc. * locale/lc-ctype.c: Revert last reversion back the other way. (_nl_postload_ctype): If current thread uses the global locale, update its tsd vars. * locale/uselocale.c (__uselocale): Update tsd vars from new locale. * hurd/hurd/threadvar.h (enum __hurd_threadvar_index): Add CTYPE_B, CTYPE_TOLOWER, CTYPE_TOUPPER. * sysdeps/generic/bits/libc-tsd.h (__libc_tsd_address): New macro. * sysdeps/mach/hurd/bits/libc-tsd.h (__libc_tsd_address): Renamed from __libc_tsd_threadvar_location. (__libc_tsd_set, __libc_tsd_get): Update uses.

/* 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. */

/* 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. */
