+.Os Ox
+.Dt FLOCKFILE 3
+.Sh NAME
+.Nm flockfile ,
+.Nm ftrylockfile ,
+.Nm funlockfile
+.Nd application level locking of stdio files
+.Sh SYNOPSIS
+.Fd #include <stdio.h>
+.Ft void
+.Fn flockfile "FILE *file"
+.Ft int
+.Fn ftrylockfile "FILE *file"
+.Ft void
+.Fn funlockfile "FILE *file"
+.Sh DESCRIPTION
+The
+.Fn flockfile ,
+.Fn ftrylockfile ,
+and
+.Fn funlockfile
+functions provide for explicit application-level locking of stdio
+.Ft "FILE *"
+objects. These functions can be used by a thread to delineate a sequence
+of I/O statements that are to be executed as a unit.
+.Pp
+The
+.Fn flockfile
+function is used by a thread to acquire ownership of a
+.Ft "FILE *"
+object.
+.Pp
+The
+.Fn ftrylockfile
+function is used by a thread to acquire ownership of a
+.Ft "FILE *"
+object if the object is available;
+.Fn ftrylockfile
+is a non-blocking version of
+.Fn flockfile .
+.Pp
+The
+.Fn funlockfile
+function is used to relinquish the ownership granted to the thread.
+The behaviour is undefined if a thread other than the current owner calls the
+.Fn funlockfile
+function.
+.Pp
+Logically, there is a lock count associated with each
+.Ft "FILE *"
+object. This count is implicitly intialized to zero when the
+.Ft "FILE *"
+object is created. The
+.Ft "FILE *"
+object is unlocked when the count is zero.
+When the count is positive, a single thread owns the
+.Ft "FILE *"
+object. When the
+.Fn flockfile
+function is called, if the count is zero or if the count is positive and
+the caller owns the
+.Ft "FILE *"
+object, the count is incremented.
+Otherwise, the calling thread is suspended, waiting for the count to
+return to zero.
+Each call to
+.Fn funlockfile
+decrements the count. This allows matching calls to
+.Fn flockfile
+(or sucessful calls to
+.Fn ftrylockfile )
+and
+.Fn funlockfile
+to be nested.
+.Pp
+Library functions that reference
+.Ft "FILE *"
+behave as if they use
+.Fn flockfile
+and
+.Fn funlockfile
+internally to obtain ownership of these
+.Ft "FILE *"
+objects.
+.Sh RETURN VALUES
+None for
+.Fn flockfile
+and
+.Fn funlockfile .
+The function
+.Fn ftrylock
+returns zero for success and non-zero to indicate that the lock cannot
+be acquired.
+.Sh ERRORS
+None.

+.Ft void
+.Fn pthread_exit "void *value_ptr"
+.Sh DESCRIPTION
+The
+.Fn pthread_exit
+function terminates the calling thread and makes the value
+.Fa value_ptr
+available to any successful join with the terminating thread. Any
+cancellation cleanup handlers that have been pushed and are not yet popped
+are popped in the reverse order that they were pushed and then executed.
+After all cancellation handlers have been executed, if the thread has any
+thread-specific data, appropriate destructor functions are called in an
+unspecified order. Thread termination does not release any application
+visible process resources, including, but not limited to, mutexes and
+file descriptors, nor does it perform any process level cleanup
+actions, including, but not limited to, calling
+.Fn atexit
+routines that may exist.
+.Pp
+An implicit call to
+.Fn pthread_exit
+is made when a thread other than the thread in which
+.Fn main
+was first invoked returns from the start routine that was used to create
+it. The function's return value serves as the thread's exit status.
+.Pp
+The behavior of
+.Fn pthread_exit
+is undefied if called from a cancellation handler or destructor function
+that was invoked as the result of an implicit or explicit call to
+.Fn pthread_exit .
+.Pp
+After a thread has terminated, the result of access to local (auto) 
+variables of the thread is undefined. Thus, references to local variables
+of the exiting thread should not be used for the
+.Fn pthread_exit
+.Fa value_ptr
+parameter value.
+.Pp
+The process will exit with an exit status of 0 after the last thread has
+been terminated. The behavior is as if the implementation called
+.Fn exit
+with a zero argument at thread termination time.
+.Pp
+.Sh RETURN VALUES

+.Sh SYNOPSIS
+.Fd #include <pthread.h>
+.Ft int
+.Fn pthread_key_create "pthread_key_t *key" "void (*destructor)(void *)"
+.Sh DESCRIPTION
+The
+.Fn pthread_key_create
+function creates a thread-specific data key visible to all threads in the
+process. Key values provided by
+.Fn pthread_key_create
+are opaque objects used to locate thread-specific data. Although the same
+key value may be used by different threads, the values bound to the key
+by
+.Fn pthread_setspecific
+are maintained on a per-thread basis and persist for the life of the calling
+thread.
+.Pp
+Upon key creation, the value NULL is associated with the new key in all
+active threads. Upon thread creation, the value NULL is associated with all
+defined keys in the new thread.
+.Pp
+An optional destructor function may be associated with each key value. At
+thread exit, if a key value has a non-NULL destructor pointer, and the
+thread has a non-NULL value associated with the key, the function pointed
+to is called with the current associated value as its sole argument. The
+order of destructor calls is unspecified if more than one destructor exists
+for a thread when it exits.
+.Pp
+If, after all the destructors have been called for all non-NULL values
+with associated destructors, there are still some non-NULL values with
+associated destructors, then the process is repeated. If, after at least
+[PTHREAD_DESTRUCTOR_ITERATIONS] iterations of destructor calls for
+outstanding non-NULL values, there are still some non-NULL values with
+associated destructors, the implementation stops calling destructors.
+.Sh RETURN VALUES
+If successful, the
+.Fn pthread_key_create
+function will store the newly created key value at the location specified by
+.Fa key
+and returns zero. Otherwise an error number will be returned to indicate
+the error.
+.Sh ERRORS
+.Fn pthread_key_create
+will fail if:
+.Bl -tag -width Er

+The system lacked the necessary resources to create another thread-specific

+The

+function deletes a thread-specific data key previously returned by
+.Fn pthread_key_create .
+The thread-specific data values associated with

+need not be NULL at the time that

+this cleanup can be done either before or after
+.Fn pthread_key_delete
+is called. Any attempt to use
+.Fa key
+following the call to
+.Fn pthread_key_delete
+results in undefined behavior.
+.Pp
+The
+.Fn pthread_key_delete
+function is callable from within destructor functions. Destructor functions
+are not invoked by

+Any destructor function that may have been associated with

+The first call to
+.Fn pthread_once
+by any thread in a process, with a given
+.Fa once_control ,
+will call the
+.Fn init_routine
+with no arguments. Subsequent calls to
+.Fn pthread_once
+with the same
+.Fa once_control
+will not call the
+.Fn init_routine .
+On return from
+.Fn pthread_once ,
+it is guaranteed that
+.Fn init_routine
+has completed. The
+.Fa once_control
+parameter is used to determine whether the associated initialization
+routine has been called.
+.Pp
+The function
+.Fn pthread_once
+is not a cancellation point. However, if
+.Fn init_routine
+is a cancellation point and is cancelled, the effect on
+.Fa once_control is as if 
+.Fn pthread_once
+was never called.
+.Pp
+The constant
+.Fa PTHREAD_ONCE_INIT
+is defined by header
+.Aq Pa pthread.h .
+.Pp
+The behavior of
+.Fn pthread_once
+is undefined if
+.Fa once_control
+has automatic storage duration or is not initialized by
+.Fa PTHREAD_ONCE_INIT .
+.Pp
+.Sh RETURN VALUES
+If successful,  the
+.Fn pthread_once
+function will return zero. Otherwise an error number will be returned to
+indicate the error.
+.Sh ERRORS
+None.

+.Sh SEE ALSO

+.Ft int
+.Fn sigwait "sont sigset_t *set" "int *sig"
+.Sh DESCRIPTION
+The
+.Fn sigwait
+function selects a pending signal from
+.Fa set ,
+atomically clears it from the system's set of pending signals, and returns
+that signal number in the location referenced by
+.Fa sig .
+If prior to the call to

+there are multiple pending instances of a single signal number,
+it is undefined whether upon successful return there are any remaining pending signals for that signal number.
+If no signal in
+.Fa set
+is pending at the time of the call,
+the thread shall be suspended until one or more becomes pending.
+The signals defined by
+.Fa set
+should have been blocked at the time of the call to
+.Fn sigwait ;
+otherwise the behaviour is undefined.
+The effect of
+.Fn sigwait
+on the signal actions for the signals in
+.Fa set
+is unspecified.
+.Pp
+If more than one thread is using
+.Fn sigwait
+to wait for the same signal,
+no more than one of these threads shall return from
+.Fn sigwait
+with the signal number.
+Which thread returns from
+.Fn sigwait
+if more than a single thread is waiting is unspecified.
+.Sh RETURN VALUES
+Upon successful completion,
+.Fn sigwait
+stores the signal number of the recived signal at the location referenced by
+.Fa sig
+and returns zero.
