* sunrpc/Makefile (routines): Add rpc_thread. (CPPFLAGS): Add -D_RPC_THREAD_SAFE. * sunrpc/rpc_thread.c: New file. * sunrpc/Versions [libc] (GLIBC_2.2.3): Export __rpc_thread_destroy. * sunrpc/auth_none.c: Don't use global variables. Access state in thread-local storage. * sunrpc/clnt_perr.c: Likewise. * sunrpc/clnt_raw.c: Likewise. * sunrpc/clnt_simp.c: Likewise. * sunrpc/key_call.c: Likewise. * sunrpc/rpc_common.c: Likewise. * sunrpc/svc.c: Likewise. * sunrpc/svc_raw.c: Likewise. * sunrpc/svc_simple.c: Likewise. * sunrpc/svcauth_des.c: Likewise. * hurd/hurd/threadvar.h (enum __hurd_threadvar_index): Add _HURD_THREADVAR_RPC_VARS. * sysdeps/generic/bits/libc-tsd.h: Mention _LIBC_TSD_KEY_RPC_VARS. * include/rpc/rpc.h: Define data structures for internal thread-local "global" variables. Based on patches by Eric Norum <eric.norum@usask.ca>.

/* 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_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. */
|
|
|
|
/* 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. */
