The user should define a union like the following to use it for arguments
for `semctl'.
union semun
{
int val; <= value for SETVAL
struct semid_ds *buf; <= buffer for IPC_STAT & IPC_SET
unsigned short int *array; <= array for GETALL & SETALL
struct seminfo *__buf; <= buffer for IPC_INFO
};
Previous versions of this file used to define this union but this is
incorrect. One can test the macro _SEM_SEMUN_UNDEFINED to see whether
one must define the union or not.
#define _SEM_SEMUN_UNDEFINED 1

<EFBFBD><EFBFBD> RETURN VALUES
Upon successful completion (that is, one of the signals
specified by set is pending or is generated) sigwaitinfo()
and sigtimedwait() will return the selected signal number.
Otherwise, the function returns -1 and sets errno to indi-
cate the error.
<EFBFBD><EFBFBD> ERRORS
The sigwaitinfo() and sigtimedwait() functions will fail if:
EINTR The wait was interrupted by an unblocked, caught
signal.
ENOSYS The sigwaitinfo() and sigtimedwait() functions are
not supported.
The sigtimedwait() function will fail if:
EAGAIN No signal specified by set was generated within
the specified timeout period.
The sigwaitinfo() and sigtimedwait() functions may fail if:
EFAULT The set, info, or timeout argument points to an
invalid address.
The sigtimedwait() function may fail if:
EINVAL The timeout argument specified a tv_nsec value
less than zero or greater than or equal to 1000
million. The system only checks for this error if
no signal is pending in set and it is necessary to
wait.

<EFBFBD><EFBFBD> RETURN VALUES
Upon successful completion, the specified signal will have
been queued, and the sigqueue() function returns 0. Other-
wise, the function returns -1 and sets errno to indicate the
error.
<EFBFBD><EFBFBD> ERRORS
The sigqueue() function will fail if:
EAGAIN No resources are available to queue the signal.
The process has already queued SIGQUEUE_MAX sig-
nals that are still pending at the receiver(s),
or a system wide resource limit has been
exceeded.
EINVAL The value of signo is an invalid or unsupported
signal number.
ENOSYS The sigqueue() function is not supported by the
system.
EPERM The process does not have the appropriate
privilege to send the signal to the receiving
process.
ESRCH The process pid does not exist.

DESCRIPTION
The sem_wait() function locks the semaphore referenced by sem
by performing a semaphore lock operation on that semaphore.
If the semaphore value is currently zero,
then the calling thread will not return from the call to sem_wait()
until it either locks the semaphore or the call is interrupted by a signal.
The sem_trywait() function locks the semaphore referenced by sem
only if the semaphore is currently not locked;
that is, if the semaphore value is currently positive.
Otherwise, it does not lock the semaphore.
Upon successful return,
the state of the semaphore is locked and remains locked
until the sem_post() function is executed and returns successfully.
The sem_wait() function is interruptible by the delivery of a signal.

NAME
sem_open - initialize and open a named semaphore
SYNOPSIS
#include <semaphore.h>
sem_t* sem_open(const char *name, int flags)
sem_t* sem_open(const char *name, int flags, mode_t mode, unsigned int value)
DESCRIPTION
The named semaphore named name is initialized and opened as specified by
the argument flags and a semaphore descriptor is returned to the calling
process.
The flags specified are formed by or'ing the following values:
O_CREAT create the semaphore if it does not exist
O_EXCL error if create and semaphore exists
If O_CREATE if specified, sem_open() requires an additional two argu-
ments. mode specifies the permissions for the semaphore as described in
chmod(2) and modified by the process' umask value (see umask(2)). The
semaphore is created with an initial value, which must be less than or
equal to SEM_VALUE_MAX.
If O_EXCL is specified and the semaphore exists, sem_open() fails. The
check for the existence of the semaphore and the creation of the
semaphore are atomic with respect to all processes calling sem_open()
with O_CREAT and O_EXCL set.
When a new semaphore is created, it is given the user ID and group ID
which coorespond to the effective user and group IDs of the calling pro-
cess. There is no visible entry in the file system for the created object
in this implementation.
The returned semaphore descriptor is available to the calling process un-
til it is closed with sem_close(), or until the caller exits or execs.
If a process makes repeated calls to sem_open(), with the same name argu-
ment, the same descriptor is returned for each successful call, unless
sem_unlink() has been called on the semaphore in the interim.
If sem_open() fails for any reason, it will return a value of SEM_FAILED
and sets errno. On success, it returns a semaphore descriptor.
ERRORS
The named semaphore is opened unless:
[EACCES] The required permissions (for reading and/or writing) are
denied for the given flags; or O_CREAT is specified, the
object does not exist, and permission to create the
semaphore is denied.
[EEXIST] O_CREAT and O_EXCL were specified and the semaphore exists.
[EINTR] The sem_open() operation was interrupted by a signal.
[EINVAL] The shm_open() operation is not supported; or O_CREAT is
specified and value exceeds SEM_VALUE_MAX.
[EMFILE] The process has already reached its limit for semaphores or
file descriptors in use.
[ENAMETOOLONG]
name exceeded SEM_NAME_LEN characters.
[ENFILE] Too many semaphores or file descriptors are open on the
system.
[ENOENT] O_CREAT is not set and the named semaphore does not exist.
[ENOSPC] O_CREAT is specified, the file does not exist, and there is
insufficient space available to create the semaphore.

HISTORY
sem_open() is specified in the POSIX Realtime Extension
(1003.1b-1993/1003.1i-1995).

dwCreationFlags
[in] Flags that control the creation of the thread.
If the CREATE_SUSPENDED flag is specified,
the thread is created in a suspended state,
and will not run until the ResumeThread function is called.
If this value is zero,
the thread runs immediately after creation.
If the STACK_SIZE_PARAM_IS_A_RESERVATION flag is specified,
the dwStackSize parameter specifies the initial reserve size of the stack.
Otherwise, dwStackSize specifies the commit size.
Windows 2000/NT and Windows Me/98/95:
The STACK_SIZE_PARAM_IS_A_RESERVATION flag is not supported.
lpThreadId
[out] Pointer to a variable that receives the thread identifier.
If this parameter is NULL, the thread identifier is not returned.
Windows Me/98/95: This parameter may not be NULL.

DESCRIPTION
The pthread_cond_timedwait()
function blocks on the specified condition variable,
which atomically releases the specified mutex
and causes the calling thread to block on the condition variable
The blocked thread may be awakened by a call to pthread_cond_signal()
or pthread_cond_broadcast(),
or if the time specified by abstime is reached.
This function atomically releases the mutex,
causing the calling thread to block on the condition variable Upon successful completion,
the mutex is locked and owned by the calling thread.
pthread_cond_timedwait() is the same as pthread_cond_wait(),
except an error is returned
if the system time equals or exceeds the time specified by abstime
before the condition variable is signaled or broadcast,
or if the absolute time specified by abstime has already passed at the time of the call.
When timeouts occur, pthread_cond_timedwait() releases and reacquires the mutex.
When using condition variables,
there should always be a boolean predicate involving shared variables related to each condition wait.
This predicate should become true only
when the thread should proceed.
Because the return from pthread_cond_timedwait() does not indicate anything about the value of this predicate,
the predicate should be reevaluated on return.
Unwanted wakeups from pthread_cond_timedwait() may occur
(since another thread could have obtained the mutex,
changed the state and released the mutex,
prior to this thread obtaining the mutex);
the reevaluation of the predicate ensures consistency.
The pthread_cond_timedwait() function is a cancellation point.
If a cancellation request is acted on while in a condition wait
when the cancellation type of a thread is set to deferred,
the mutex is reacquired before calling the first cancellation cleanup handler.
In other words, the thread is unblocked,
allowed to execute up to the point of returning from the call pthread_cond_timedwait(),
but instead of returning to the caller, it performs the thread cancellation.
--------------------------------------------------------------------------------
PARAMETERS
cond
Is the condition variable to wait on.
mutex
Is the mutex associated with the condition variable.
abstime
Is the absolute time at which the wait is cancelled if not signaled or broadcast.
--------------------------------------------------------------------------------
RETURN VALUES
On success, pthread_cond_timedwait() returns 0.
On error, one of the following values is returned:
EINVAL
cond does not refer to an initialized condition variable,
or mutex does not refer to an initialized mutex.
Different mutexes were specified in multiple waits on cond.
mutex is not owned by the caller.
EFAULT
cond, mutex, or abstime is an invalid pointer.
ETIMEDOUT
The specified absolute time has passed.

<EFBFBD><EFBFBD> int sched_yield(void) : IN <sched.h>
A process can relinquish the processor voluntarily
without blocking by calling sched_yield().
The process will then be moved to the end of the queue
for its static priority and a new process gets to run.
Note: If the current process is the only process
in the highest priority list at that time,
this process will continue
to run after a call to sched_yield().
POSIX systems on which sched_yield() is available define _POSIX_PRIORITY_SCHEDULING in <unistd.h>.
RETURN VALUE
On success, sched_yield() returns 0.
On error, -1 is returned, and errno is set appropriately.
