README

These are the source files for the programming examples in
"Programming With POSIX(r) Threads". The Makefile is pre-configured
for Digital UNIX, but includes the appropriate definitions to build on
Solaris (uncomment the Solaris lines and comment the Digital UNIX
lines).

alarm.c				Simple synchronous alarm clock
alarm_cond.c			Threaded alarm clock using condition variable
alarm_fork.c			Alarm clock using fork asychrony
alarm_mutex.c			Threaded alarm clock using mutex
alarm_thread.c			Alarm clock using thread asynchrony
atfork.c			Demonstrate pthread_atfork()
backoff.c			Demonstrate mutex hierarchy backoff
barrier.c			Implementation of barrier package
barrier_main.c			Demonstrate use of barrier package
cancel.c			Demonstrate cancellation
cancel_async.c			Demonstrate asyncronous cancellation
cancel_cleanup.c		Demonstrate cancellation cleanup
cancel_disable.c		Demonstrate disabling cancellation
cancel_subcontract.c		Demonstrate cancellation of "subcontractors"
cond.c				Demonstrate use of condition variables
cond_attr.c			Demonstrate condition variable attributes
cond_dynamic.c			Demonstrate dynamic init of condition variable
cond_static.c			Demonstrate static init of condition variable
crew.c				A simple threaded work crew
flock.c				Demonstrate use of file locking
getlogin.c			Demonstrate reentrant user functions
hello.c				Demonstrate thread creation
inertia.c			Demonstrate "thread inertia" errors
lifecycle.c			Demonstrate "thread lifecycle"
mutex_attr.c			Demonstrate mutex attributes
mutex_dynamic.c			Demonstrate dynamic initialization of mutex
mutex_static.c			Demonstrate static initialization of mutex
once.c				Demonstrate use of pthread_once()
pipe.c				A simple threaded pipeline
putchar.c			Demonstrate thread-safe use of putchar()
rwlock.c			Implementation of read/write lock package
rwlock_main.c			Demonstrate use of read/write lock package
rwlock_try_main.c		Demonstrate use of read/write lock package
sched_attr.c			Demonstrate thread scheduling attributes
sched_thread.c			Demonstrate use of thread scheduling functions
semaphore_signal.c		Demonstrate use of semaphores with signals
semaphore_wait.c		Demonstrate use of semaphores
server.c			A simple threaded client/server program
sigev_thread.c			Demonstrate use of SIGEV_THREAD mechanism
sigwait.c			Demonstrate use of sigwait()
susp.c				Demonstrate use of pthread_kill()
thread.c			Demonstrate simple concurrent I/O
thread_attr.c			Demonstrate thread attributes
thread_error.c			Demonstrate POSIX thread error mechanism
trylock.c			Demonstrate use of pthread_mutex_trylock()
tsd_destructor.c		Demonstrate thread-specific data destructors
tsd_once.c			Demonstrate thread-specific data key creation
workq.c				Implementation of work queue package
workq_main.c			Demonstrate use of work queue package

Header files:

barrier.h			Definitions for barrier package
errors.h			General headers and error macros
rwlock.h			Definitions for read/write lock package
workq.h				Definitions for work queue package

Programs with arguments or special behavior:

alarm, alarm_fork,		The alarm programs will prompt for
alarm_thread, alarm_mutex,	commands until terminated by ^D
alarm_cond			(EOF). Commands are "<n> <s>" where <s>
				(the remainder of the line) is a
				message to print after <n> seconds.
atfork [hang]			Run with an argument of 0 to omit
				atfork handlers -- program will hang.
backoff [backoff [delay]]	Run with first argument of 0, will not
				back off on mutex collision, and will
				usually hang. Second argument can be
				specified greater than 0 to yield
				(increasing chances of hang on
				uniprocessor), or less than 0 to sleep
				for a second.
crew string path		First argument is a search string,
				second is a file path.
flock				Threads will prompt alternately for
				input.
pipe				Prompts for integers to feed to
				pipeline; enter "=" to pop a result.
putchar [unsync]		Run with argument of 0 to concurrently
				call putchar_unlocked from multiple
				threads.
server				Threads each prompt for input, and
				echo it 3 times -- server prevents
				output while waiting for input.
sigwait				Waits for 5 SIGINT signals (^C)
thread				One thread writes to stdout while
				another waits for input from
				stdin. (Satisfy the read to exit.)
