-vda: here is why:
-headers contain libc_hidden_proto(foo).
-In libpthread/linuxthreads.old/sysdeps/pthread/bits/libc-lock.h
-adding libc_hidden_proto(foo) just before weak_extern (__pthread_initialize)
-will not warn:
-    /* libc_hidden_proto(foo) */
-    weak_extern (__pthread_initialize)
-    /* libc_hidden_proto(foo) */
-but adding after will! Which is extremely strange -
-weak_extern expands into just "#pragma weak __pthread_initialize".
-TODO: determine whether it is a gcc bug or what
-(see gcc.gnu.org/PR36282).
-For now, just include all headers before internals.h

-This chapter describes the pthreads (POSIX threads) library.  This
-library provides support functions for multithreaded programs: thread
-primitives, synchronization objects, and so forth.  It also implements
-POSIX 1003.1b semaphores (not to be confused with System V semaphores).
-
-The threads operations (@samp{pthread_*}) do not use @var{errno}.
-Instead they return an error code directly.  The semaphore operations do
-use @var{errno}.

-* Basic Thread Operations::     Creating, terminating, and waiting for threads.
-* Thread Attributes::           Tuning thread scheduling.
-* Cancellation::                Stopping a thread before it's done.
-* Cleanup Handlers::            Deallocating resources when a thread is

-@deftypefun int pthread_create (pthread_t * @var{thread}, pthread_attr_t * @var{attr}, void * (*@var{start_routine})(void *), void * @var{arg})
-@code{pthread_create} creates a new thread of control that executes
-concurrently with the calling thread. The new thread calls the
-function @var{start_routine}, passing it @var{arg} as first argument. The
-new thread terminates either explicitly, by calling @code{pthread_exit},
-or implicitly, by returning from the @var{start_routine} function. The
-latter case is equivalent to calling @code{pthread_exit} with the result
-returned by @var{start_routine} as exit code.
-
-The @var{attr} argument specifies thread attributes to be applied to the
-new thread. @xref{Thread Attributes}, for details. The @var{attr}
-argument can also be @code{NULL}, in which case default attributes are
-used: the created thread is joinable (not detached) and has an ordinary
-(not realtime) scheduling policy.
-
-On success, the identifier of the newly created thread is stored in the
-location pointed by the @var{thread} argument, and a 0 is returned. On
-error, a non-zero error code is returned.
-
-This function may return the following errors:
-@table @code
-@item EAGAIN
-Not enough system resources to create a process for the new thread,
-or more than @code{PTHREAD_THREADS_MAX} threads are already active.

-@deftypefun void pthread_exit (void *@var{retval})
-@code{pthread_exit} terminates the execution of the calling thread.  All
-cleanup handlers (@pxref{Cleanup Handlers}) that have been set for the
-calling thread with @code{pthread_cleanup_push} are executed in reverse
-order (the most recently pushed handler is executed first). Finalization
-functions for thread-specific data are then called for all keys that
-have non-@code{NULL} values associated with them in the calling thread
-(@pxref{Thread-Specific Data}).  Finally, execution of the calling
-thread is stopped.
-
-The @var{retval} argument is the return value of the thread. It can be
-retrieved from another thread using @code{pthread_join}.
-
-The @code{pthread_exit} function never returns.
-@end deftypefun

-@comment pthread.h
-@comment POSIX
-@deftypefun int pthread_cancel (pthread_t @var{thread})
-
-@code{pthread_cancel} sends a cancellation request to the thread denoted
-by the @var{thread} argument.  If there is no such thread,
-@code{pthread_cancel} fails and returns @code{ESRCH}.  Otherwise it
-returns 0. @xref{Cancellation}, for details.
-@end deftypefun
-
-@comment pthread.h
-@comment POSIX
-@deftypefun int pthread_join (pthread_t @var{th}, void **thread_@var{return})
-@code{pthread_join} suspends the execution of the calling thread until
-the thread identified by @var{th} terminates, either by calling
-@code{pthread_exit} or by being canceled.
-
-If @var{thread_return} is not @code{NULL}, the return value of @var{th}
-is stored in the location pointed to by @var{thread_return}.  The return
-value of @var{th} is either the argument it gave to @code{pthread_exit},
-or @code{PTHREAD_CANCELED} if @var{th} was canceled.
-
-The joined thread @code{th} must be in the joinable state: it must not
-have been detached using @code{pthread_detach} or the
-@code{PTHREAD_CREATE_DETACHED} attribute to @code{pthread_create}.
-
-When a joinable thread terminates, its memory resources (thread
-descriptor and stack) are not deallocated until another thread performs
-@code{pthread_join} on it. Therefore, @code{pthread_join} must be called
-once for each joinable thread created to avoid memory leaks.
-
-At most one thread can wait for the termination of a given
-thread. Calling @code{pthread_join} on a thread @var{th} on which
-another thread is already waiting for termination returns an error.
-
-@code{pthread_join} is a cancellation point. If a thread is canceled
-while suspended in @code{pthread_join}, the thread execution resumes
-immediately and the cancellation is executed without waiting for the
-@var{th} thread to terminate. If cancellation occurs during
-@code{pthread_join}, the @var{th} thread remains not joined.
-
-On success, the return value of @var{th} is stored in the location
-pointed to by @var{thread_return}, and 0 is returned. On error, one of
-the following values is returned:
-@table @code
-@item ESRCH
-No thread could be found corresponding to that specified by @var{th}.
-@item EINVAL
-The @var{th} thread has been detached, or another thread is already
-waiting on termination of @var{th}.
-@item EDEADLK
-The @var{th} argument refers to the calling thread.

-
-Threads have a number of attributes that may be set at creation time.
-This is done by filling a thread attribute object @var{attr} of type
-@code{pthread_attr_t}, then passing it as second argument to
-@code{pthread_create}. Passing @code{NULL} is equivalent to passing a
-thread attribute object with all attributes set to their default values.
-
-Attribute objects are consulted only when creating a new thread.  The
-same attribute object can be used for creating several threads.
-Modifying an attribute object after a call to @code{pthread_create} does
-not change the attributes of the thread previously created.

-@deftypefun int pthread_attr_init (pthread_attr_t *@var{attr})
-@code{pthread_attr_init} initializes the thread attribute object
-@var{attr} and fills it with default values for the attributes. (The
-default values are listed below for each attribute.)
-
-Each attribute @var{attrname} (see below for a list of all attributes)

-
-In the joinable state, another thread can synchronize on the thread

-
-A thread created in the joinable state can later be put in the detached

-
-@item schedpolicy
-Select the scheduling policy for the thread: one of @code{SCHED_OTHER}
-(regular, non-realtime scheduling), @code{SCHED_RR} (realtime,

-
-@item schedparam
-Change the scheduling parameter (the scheduling priority)
-for the thread.  The default is 0.
-
-This attribute is not significant if the scheduling policy is

-(value @code{PTHREAD_INHERIT_SCHED}).  The default is

-
-@item scope
-Choose the scheduling contention scope for the created thread.  The
-default is @code{PTHREAD_SCOPE_SYSTEM}, meaning that the threads contend
-for CPU time with all processes running on the machine. In particular,
-thread priorities are interpreted relative to the priorities of all
-other processes on the machine. The other possibility,

-@node Cancellation
-@section Cancellation
-
-Cancellation is the mechanism by which a thread can terminate the
-execution of another thread. More precisely, a thread can send a
-cancellation request to another thread. Depending on its settings, the
-target thread can then either ignore the request, honor it immediately,
-or defer it till it reaches a cancellation point.  When threads are
-first created by @code{pthread_create}, they always defer cancellation
-requests.
-
-When a thread eventually honors a cancellation request, it behaves as if
-@code{pthread_exit(PTHREAD_CANCELED)} was called.  All cleanup handlers
-are executed in reverse order, finalization functions for
-thread-specific data are called, and finally the thread stops executing.
-If the canceled thread was joinable, the return value
-@code{PTHREAD_CANCELED} is provided to whichever thread calls
-@var{pthread_join} on it. See @code{pthread_exit} for more information.
-
-Cancellation points are the points where the thread checks for pending
-cancellation requests and performs them.  The POSIX threads functions
-@code{pthread_join}, @code{pthread_cond_wait},
-@code{pthread_cond_timedwait}, @code{pthread_testcancel},
-@code{sem_wait}, and @code{sigwait} are cancellation points.  In
-addition, these system calls are cancellation points:

-@node Cleanup Handlers
-@section Cleanup Handlers
-
-Cleanup handlers are functions that get called when a thread terminates,
-either by calling @code{pthread_exit} or because of
-cancellation. Cleanup handlers are installed and removed following a
-stack-like discipline.
-
-The purpose of cleanup handlers is to free the resources that a thread
-may hold at the time it terminates. In particular, if a thread exits or
-is canceled while it owns a locked mutex, the mutex will remain locked
-forever and prevent other threads from executing normally. The best way
-to avoid this is, just before locking the mutex, to install a cleanup
-handler whose effect is to unlock the mutex. Cleanup handlers can be
-used similarly to free blocks allocated with @code{malloc} or close file
-descriptors on thread termination.
-
-Here is how to lock a mutex @var{mut} in such a way that it will be
-unlocked if the thread is canceled while @var{mut} is locked:
-
-@smallexample
-pthread_cleanup_push(pthread_mutex_unlock, (void *) &mut);
-pthread_mutex_lock(&mut);
-/* do some work */
-pthread_mutex_unlock(&mut);
-pthread_cleanup_pop(0);
-@end smallexample
-
-Equivalently, the last two lines can be replaced by
-
-@smallexample
-pthread_cleanup_pop(1);
-@end smallexample
-
-Notice that the code above is safe only in deferred cancellation mode
-(see @code{pthread_setcanceltype}). In asynchronous cancellation mode, a
-cancellation can occur between @code{pthread_cleanup_push} and
-@code{pthread_mutex_lock}, or between @code{pthread_mutex_unlock} and
-@code{pthread_cleanup_pop}, resulting in both cases in the thread trying
-to unlock a mutex not locked by the current thread. This is the main
-reason why asynchronous cancellation is difficult to use.
-
-If the code above must also work in asynchronous cancellation mode,
-then it must switch to deferred mode for locking and unlocking the
-mutex:
-
-@smallexample
-pthread_setcanceltype(PTHREAD_CANCEL_DEFERRED, &oldtype);
-pthread_cleanup_push(pthread_mutex_unlock, (void *) &mut);
-pthread_mutex_lock(&mut);
-/* do some work */
-pthread_cleanup_pop(1);
-pthread_setcanceltype(oldtype, NULL);
-@end smallexample
-
-The code above can be rewritten in a more compact and efficient way,
-using the non-portable functions @code{pthread_cleanup_push_defer_np}
-and @code{pthread_cleanup_pop_restore_np}:
-
-@smallexample
-pthread_cleanup_push_defer_np(pthread_mutex_unlock, (void *) &mut);
-pthread_mutex_lock(&mut);
-/* do some work */
-pthread_cleanup_pop_restore_np(1);

-
-@code{pthread_cleanup_push} installs the @var{routine} function with
-argument @var{arg} as a cleanup handler. From this point on to the
-matching @code{pthread_cleanup_pop}, the function @var{routine} will be
-called with arguments @var{arg} when the thread terminates, either
-through @code{pthread_exit} or by cancellation. If several cleanup
-handlers are active at that point, they are called in LIFO order: the
-most recently installed handler is called first.

-
-@comment pthread.h

-@deftypefun void pthread_cleanup_pop (int @var{execute})

-@var{arg}. If the @var{execute} argument is 0, the handler is only
-removed but not executed.

-@node Mutexes
-@section Mutexes
-
-A mutex is a MUTual EXclusion device, and is useful for protecting
-shared data structures from concurrent modifications, and implementing
-critical sections and monitors.
-
-A mutex has two possible states: unlocked (not owned by any thread),
-and locked (owned by one thread). A mutex can never be owned by two
-different threads simultaneously. A thread attempting to lock a mutex
-that is already locked by another thread is suspended until the owning
-thread unlocks the mutex first.
-
-None of the mutex functions is a cancellation point, not even
-@code{pthread_mutex_lock}, in spite of the fact that it can suspend a
-thread for arbitrary durations. This way, the status of mutexes at
-cancellation points is predictable, allowing cancellation handlers to
-unlock precisely those mutexes that need to be unlocked before the
-thread stops executing. Consequently, threads using deferred
-cancellation should never hold a mutex for extended periods of time.
-
-It is not safe to call mutex functions from a signal handler.  In
-particular, calling @code{pthread_mutex_lock} or
-@code{pthread_mutex_unlock} from a signal handler may deadlock the
-calling thread.

-@node Thread-Specific Data
-@section Thread-Specific Data
-
-Programs often need global or static variables that have different
-values in different threads. Since threads share one memory space, this
-cannot be achieved with regular variables. Thread-specific data is the
-POSIX threads answer to this need.
-
-Each thread possesses a private memory block, the thread-specific data
-area, or TSD area for short. This area is indexed by TSD keys. The TSD
-area associates values of type @code{void *} to TSD keys. TSD keys are
-common to all threads, but the value associated with a given TSD key can
-be different in each thread.
-
-For concreteness, the TSD areas can be viewed as arrays of @code{void *}
-pointers, TSD keys as integer indices into these arrays, and the value
-of a TSD key as the value of the corresponding array element in the
-calling thread.
-
-When a thread is created, its TSD area initially associates @code{NULL}
-with all keys.

-@deftypefun int pthread_key_create (pthread_key_t *@var{key}, void (*destr_function) (void *))
-@code{pthread_key_create} allocates a new TSD key. The key is stored in
-the location pointed to by @var{key}. There is a limit of
-@code{PTHREAD_KEYS_MAX} on the number of keys allocated at a given
-time. The value initially associated with the returned key is
-@code{NULL} in all currently executing threads.
-
-The @var{destr_function} argument, if not @code{NULL}, specifies a
-destructor function associated with the key. When a thread terminates
-via @code{pthread_exit} or by cancellation, @var{destr_function} is
-called on the value associated with the key in that thread. The
-@var{destr_function} is not called if a key is deleted with
-@code{pthread_key_delete} or a value is changed with
-@code{pthread_setspecific}.  The order in which destructor functions are
-called at thread termination time is unspecified.
-
-Before the destructor function is called, the @code{NULL} value is
-associated with the key in the current thread.  A destructor function
-might, however, re-associate non-@code{NULL} values to that key or some
-other key.  To deal with this, if after all the destructors have been
-called for all non-@code{NULL} values, there are still some
-non-@code{NULL} values with associated destructors, then the process is

-that it's the thread doing the @code{sigwait} that will receive the signal.
-The best way to achieve this is block those signals before any threads
-are created, and never unblock them in the program other than by
-calling @code{sigwait}.
-
-Signal handling in LinuxThreads departs significantly from the POSIX
-standard. According to the standard, ``asynchronous'' (external) signals
-are addressed to the whole process (the collection of all threads),
-which then delivers them to one particular thread. The thread that
-actually receives the signal is any thread that does not currently block
-the signal.
-
-In LinuxThreads, each thread is actually a kernel process with its own
-PID, so external signals are always directed to one particular thread.
-If, for instance, another thread is blocked in @code{sigwait} on that
-signal, it will not be restarted.
-
-The LinuxThreads implementation of @code{sigwait} installs dummy signal
-handlers for the signals in @var{set} for the duration of the
-wait. Since signal handlers are shared between all threads, other
-threads must not attach their own signal handlers to these signals, or
-alternatively they should all block these signals (which is recommended
-anyway).
-
-@node Threads and Fork
-@section Threads and Fork
-
-It's not intuitively obvious what should happen when a multi-threaded POSIX
-process calls @code{fork}. Not only are the semantics tricky, but you may
-need to write code that does the right thing at fork time even if that code
-doesn't use the @code{fork} function. Moreover, you need to be aware of
-interaction between @code{fork} and some library features like
-@code{pthread_once} and stdio streams.
-
-When @code{fork} is called by one of the threads of a process, it creates a new
-process which is copy of the  calling process. Effectively, in addition to
-copying certain system objects, the function takes a snapshot of the memory
-areas of the parent process, and creates identical areas in the child.
-To make matters more complicated, with threads it's possible for two or more
-threads to concurrently call fork to create two or more child processes.
-
-The child process has a copy of the address space of the parent, but it does
-not inherit any of its threads. Execution of the child process is carried out
-by a new thread which returns from @code{fork} function with a return value of
-zero; it is the only thread in the child process.  Because threads are not
-inherited across fork, issues arise. At the time of the call to @code{fork},
-threads in the parent process other than the one calling @code{fork} may have
-been executing critical regions of code.  As a result, the child process may
-get a copy of objects that are not in a well-defined state.  This potential
-problem affects all components of the program.
-
-Any program component which will continue being used in a child process must
-correctly handle its state during @code{fork}. For this purpose, the POSIX
-interface provides the special function @code{pthread_atfork} for installing
-pointers to handler functions which are called from within @code{fork}.
-
-@comment pthread.h
-@comment POSIX
-@deftypefun int pthread_atfork (void (*@var{prepare})(void), void (*@var{parent})(void), void (*@var{child})(void))
-
-@code{pthread_atfork} registers handler functions to be called just
-before and just after a new process is created with @code{fork}. The
-@var{prepare} handler will be called from the parent process, just
-before the new process is created. The @var{parent} handler will be
-called from the parent process, just before @code{fork} returns. The
-@var{child} handler will be called from the child process, just before
-@code{fork} returns.
-
-@code{pthread_atfork} returns 0 on success and a non-zero error code on
-error.
-
-One or more of the three handlers @var{prepare}, @var{parent} and
-@var{child} can be given as @code{NULL}, meaning that no handler needs
-to be called at the corresponding point.
-
-@code{pthread_atfork} can be called several times to install several
-sets of handlers. At @code{fork} time, the @var{prepare} handlers are
-called in LIFO order (last added with @code{pthread_atfork}, first
-called before @code{fork}), while the @var{parent} and @var{child}
-handlers are called in FIFO order (first added, first called).
-
-If there is insufficient memory available to register the handlers,
-@code{pthread_atfork} fails and returns @code{ENOMEM}.  Otherwise it
-returns 0.
-
-The functions @code{fork} and @code{pthread_atfork} must not be regarded as
-reentrant from the context of the handlers.  That is to say, if a
-@code{pthread_atfork} handler invoked from within @code{fork} calls
-@code{pthread_atfork} or @code{fork}, the behavior is undefined.
-
-Registering a triplet of handlers is an atomic operation with respect to fork.
-If new handlers are registered at about the same time as a fork occurs, either
-all three handlers will be called, or none of them will be called.
-
-The handlers are inherited by the child process, and there is no
-way to remove them, short of using @code{exec} to load a new
-pocess image.
-
-@end deftypefun
-
-To understand the purpose of @code{pthread_atfork}, recall that
-@code{fork} duplicates the whole memory space, including mutexes in
-their current locking state, but only the calling thread: other threads
-are not running in the child process.  The mutexes are not usable after
-the @code{fork} and must be initialized with @code{pthread_mutex_init}
-in the child process.  This is a limitation of the current
-implementation and might or might not be present in future versions.
-
-To avoid this, install handlers with @code{pthread_atfork} as follows: have the
-@var{prepare} handler lock the mutexes (in locking order), and the
-@var{parent} handler unlock the mutexes. The @var{child} handler should reset
-the mutexes using @code{pthread_mutex_init}, as well as any other
-synchronization objects such as condition variables.
-
-Locking the global mutexes before the fork ensures that all other threads are
-locked out of the critical regions of code protected by those mutexes.  Thus
-when @code{fork} takes a snapshot of the parent's address space, that snapshot
-will copy valid, stable data.  Resetting the synchronization objects in the
-child process will ensure they are properly cleansed of any artifacts from the
-threading subsystem of the parent process. For example, a mutex may inherit
-a wait queue of threads waiting for the lock; this wait queue makes no sense
-in the child process. Initializing the mutex takes care of this.
-
-@node Streams and Fork
-@section Streams and Fork
-
-The GNU standard I/O library has an internal mutex which guards the internal
-linked list of all standard C FILE objects. This mutex is properly taken care
-of during @code{fork} so that the child receives an intact copy of the list.
-This allows the @code{fopen} function, and related stream-creating functions,
-to work correctly in the child process, since these functions need to insert
-into the list.
-
-However, the individual stream locks are not completely taken care of.  Thus
-unless the multithreaded application takes special precautions in its use of
-@code{fork}, the child process might not be able to safely use the streams that
-it inherited from the parent.   In general, for any given open stream in the
-parent that is to be used by the child process, the application must ensure
-that that stream is not in use by another thread when @code{fork} is called.
-Otherwise an inconsistent copy of the stream object be produced. An easy way to
-ensure this is to use @code{flockfile} to lock the stream prior to calling
-@code{fork} and then unlock it with @code{funlockfile} inside the parent
-process, provided that the parent's threads properly honor these locks.
-Nothing special needs to be done in the child process, since the library
-internally resets all stream locks.
-
-Note that the stream locks are not shared between the parent and child.
-For example, even if you ensure that, say, the stream @code{stdout} is properly
-treated and can be safely used in the child, the stream locks do not provide
-an exclusion mechanism between the parent and child. If both processes write
-to @code{stdout}, strangely interleaved output may result regardless of
-the explicit use of @code{flockfile} or implicit locks.
-
-Also note that these provisions are a GNU extension; other systems might not
-provide any way for streams to be used in the child of a multithreaded process.
-POSIX requires that such a child process confines itself to calling only
-asynchronous safe functions, which excludes much of the library, including
-standard I/O.

-@deftypefun int pthread_equal (pthread_t thread1, pthread_t thread2)
-@code{pthread_equal} determines if two thread identifiers refer to the same

-the same thread. Otherwise, 0 is returned.

-@deftypefun int pthread_detach (pthread_t @var{th})
-@code{pthread_detach} puts the thread @var{th} in the detached
-state. This guarantees that the memory resources consumed by @var{th}
-will be freed immediately when @var{th} terminates. However, this
-prevents other threads from synchronizing on the termination of @var{th}
-using @code{pthread_join}.
-
-A thread can be created initially in the detached state, using the
-@code{detachstate} attribute to @code{pthread_create}. In contrast,
-@code{pthread_detach} applies to threads created in the joinable state,
-and which need to be put in the detached state later.
-
-After @code{pthread_detach} completes, subsequent attempts to perform
-@code{pthread_join} on @var{th} will fail. If another thread is already
-joining the thread @var{th} at the time @code{pthread_detach} is called,
-@code{pthread_detach} does nothing and leaves @var{th} in the joinable
-state.
-
-On success, 0 is returned. On error, one of the following codes is
-returned:
-@table @code
-@item ESRCH
-No thread could be found corresponding to that specified by @var{th}
-@item EINVAL
-The thread @var{th} is already in the detached state

-@deftypefun void pthread_kill_other_threads_np (@var{void})
-@code{pthread_kill_other_threads_np} is a non-portable LinuxThreads extension.
-It causes all threads in the program to terminate immediately, except
-the calling thread which proceeds normally. It is intended to be
-called just before a thread calls one of the @code{exec} functions,
-e.g. @code{execve}.
-
-Termination of the other threads is not performed through
-@code{pthread_cancel} and completely bypasses the cancellation
-mechanism. Hence, the current settings for cancellation state and
-cancellation type are ignored, and the cleanup handlers are not
-executed in the terminated threads.
-
-According to POSIX 1003.1c, a successful @code{exec*} in one of the
-threads should automatically terminate all other threads in the program.
-This behavior is not yet implemented in LinuxThreads.  Calling
-@code{pthread_kill_other_threads_np} before @code{exec*} achieves much
-of the same behavior, except that if @code{exec*} ultimately fails, then
-all other threads are already killed.
-@end deftypefun

-@comment pthread.h
-@comment POSIX
-@deftypefun int pthread_once (pthread_once_t *once_@var{control}, void (*@var{init_routine}) (void))
-
-The purpose of @code{pthread_once} is to ensure that a piece of
-initialization code is executed at most once. The @var{once_control}
-argument points to a static or extern variable statically initialized
-to @code{PTHREAD_ONCE_INIT}.
-
-The first time @code{pthread_once} is called with a given
-@var{once_control} argument, it calls @var{init_routine} with no
-argument and changes the value of the @var{once_control} variable to
-record that initialization has been performed. Subsequent calls to
-@code{pthread_once} with the same @code{once_control} argument do
-nothing.
-
-If a thread is cancelled while executing @var{init_routine}
-the state of the @var{once_control} variable is reset so that
-a future call to @code{pthread_once} will call the routine again.
-
-If the process forks while one or more threads are executing
-@code{pthread_once} initialization routines, the states of their respective
-@var{once_control} variables will appear to be reset in the child process so
-that if the child calls @code{pthread_once}, the routines will be executed.
-
-@code{pthread_once} always returns 0.

-@deftypefun int pthread_setschedparam (pthread_t target_@var{thread}, int @var{policy}, const struct sched_param *@var{param})

-@code{pthread_setschedparam} sets the scheduling parameters for the
-thread @var{target_thread} as indicated by @var{policy} and
-@var{param}. @var{policy} can be either @code{SCHED_OTHER} (regular,
-non-realtime scheduling), @code{SCHED_RR} (realtime, round-robin) or
-@code{SCHED_FIFO} (realtime, first-in first-out). @var{param} specifies
-the scheduling priority for the two realtime policies.  See
-@code{sched_setpolicy} for more information on scheduling policies.
-
-The realtime scheduling policies @code{SCHED_RR} and @code{SCHED_FIFO}
-are available only to processes with superuser privileges.
-
-On success, @code{pthread_setschedparam} returns 0.  On error it returns
-one of the following codes:
-@table @code
-@item EINVAL
-@var{policy} is not one of @code{SCHED_OTHER}, @code{SCHED_RR},
-@code{SCHED_FIFO}, or the priority value specified by @var{param} is not

-
-@item EPERM
-Realtime scheduling was requested but the calling process does not have
-sufficient privileges.

-in the locations pointed to by @var{policy} and @var{param},

-/* The status field of a spinlock is a pointer whose least significant
-   bit is a locked flag.
-
-   Thus the field values have the following meanings:
-
-   status == 0:       spinlock is free
-   status == 1:       spinlock is taken; no thread is waiting on it
-
-   (status & 1) == 1: spinlock is taken and (status & ~1L) is a
-                      pointer to the first waiting thread; other
-		      waiting threads are linked via the p_nextlock
-		      field.
-   (status & 1) == 0: same as above, but spinlock is not taken.
-
-   The waiting list is not sorted by priority order.
-   Actually, we always insert at top of list (sole insertion mode
-   that can be performed without locking).
-   For __pthread_unlock, we perform a linear search in the list
-   to find the highest-priority, oldest waiting thread.
-   This is safe because there are no concurrent __pthread_unlock
-   operations -- only the thread that locked the mutex can unlock it. */

-
-
-/* An architecture-specific version of this file has to defined a
-   number of symbols:
-
-     TLS_TCB_AT_TP  or  TLS_DTV_AT_TP
-
-     The presence of one of these symbols signals which variant of
-     the TLS ABI is used.  There are in the moment two variants
-     available:
-
-     * the thread pointer points to a thread control block
-
-     * the thread pointer points to the dynamic thread vector
-
-
-     TLS_TCB_SIZE
-
-     This is the size of the thread control block structure.  How
-     this is actually defined depends on the ABI.  The thread control
-     block could be internal descriptor of the thread library or
-     just a data structure which allows finding the DTV.
-
-     TLS_INIT_TCB_SIZE
-
-     Similarly, but this value is only used at startup and in the
-     dynamic linker itself.  There are no threads in use at that time.
-
-
-     TLS_TCB_ALIGN
-
-     Alignment requirements for the TCB structure.
-
-     TLS_INIT_TCB_ALIGN
-
-     Similarly, but for the structure used at startup time.
-
-
-     INSTALL_DTV(tcb, init_dtv)
-
-     This macro must install the given initial DTV into the thread control
-     block TCB.  The normal runtime functionality must then be able to
-     use the value.
-
-
-     TLS_INIT_TP(tcb, firstcall)
-
-     This macro must initialize the thread pointer to enable normal TLS
-     operation.  The first parameter is a pointer to the thread control
-     block.  The second parameter specifies whether this is the first
-     call for the TCB.  ld.so calls this macro more than once.
-
-
-     THREAD_DTV()
-
-     This macro returns the address of the DTV of the current thread.
-     This normally is done using the the thread register which points
-     to the dtv or the TCB (from which the DTV can found).
