It’s best to read the relevant literature, some of which Butenhof includes in butenho bibliography but look out for newer work. You then move to more advanced topics such as attributes objects, thread-specific data, and realtime scheduling.
Faulty assumptions about memory visibility that happened to be true for single core machines are often demonstrably false for multicore and multiprocessor machines, so the dangers of deadlock, livelock and race conditions are ever more present.
The primary advantage of threaded programming is that it enables your applications to accomplish more than one task at the same time by using the number-crunching power of multiprocessor parallelism an With this practical book, you will attain a solid understanding of threads and will discover butennhof to put this powerful mode of programming to work in real-world applications.

Dan Nuffer rated it really liked it Jan 16, Programming with POSIX threads is therefore lacking a good description of the now-standard APIs — although Butenhof devotes a section in Chapter 7 to implementing read-write locks, this is now only of historical interest, as the semantics are different from those in the new standard.

The POSIX thread libraries are a standards based thread API for C/C++.It allows one to spawn a new concurrent process flow. It is most effectiveon multi-processor or multi-core systems where the process flow can be scheduled to run on another processor thus gaining speed through parallel or distributed processing.Threads require less overhead than 'forking' or spawning a new process because the system does not initialize a new system virtual memory space and environment forthe process. While most effective on a multiprocessor system, gains arealso found on uniprocessor systems which exploit latency in I/O and othersystem functions which may halt process execution. (One thread may executewhile another is waiting for I/O or some other system latency.)Parallel programming technologies such as MPI and PVM are used in a distributedcomputing environment while threads are limited to a single computer system.All threads within a process share the same address space.A thread is spawned by defining a function and it's arguments which willbe processed in the thread.The purpose of using the POSIX thread library in your software is to execute software faster. |

Example: pthread1.c Compile:
Run: ./a.out Results: Details:
The threads library provides three synchronization mechanisms:
Mutexes:Mutexes are used to prevent data inconsistencies due to race conditions.A race condition often occurs when two or more threads need to perform operations on the same memory area, but the results of computations depends on the order in which these operations are performed. Mutexes are used for serializing shared resources. Anytime a global resource is accessed by more than one thread the resource should have a Mutex associated with it. One can apply a mutex to protect a segment of memory ('critical region') from other threads.Mutexes can be applied only to threads in a single process and do not workbetween processes as do semaphores.Example threaded function:
If register load and store operations for the incrementing of variable counteroccurs with unfortunate timing, it is theoretically possible to have each thread increment and overwrite the same variable with the same value.Another possibility is that thread two would first increment counter locking out thread one until complete and then thread one would increment it to 2.
Code listing: mutex1.c Compile: cc -lpthread mutex1.c Run: ./a.out Results: When a mutex lock is attempted against a mutex which is held by another thread,the thread is blocked until the mutex is unlocked.When a thread terminates, the mutex does not unless explicitly unlocked.Nothing happens by default. Joins:A join is performed when one wants to wait for a thread to finish. A threadcalling routine may launch multiple threads then wait for them to finish to get the results. One wait for the completion of the threads with a join.Sample code: join1.c Compile: cc -lpthread join1.c Run: ./a.out Results: Condition Variables:A condition variable is a variable of type pthread_cond_t and isused with the appropriate functions for waiting and later, process continuation.The condition variable mechanism allows threads to suspend execution and relinquish the processor until some condition is true.A condition variable must always be associated with a mutexto avoid a race condition created by one thread preparing to wait and another threadwhich may signal the condition before the first thread actually waits on itresulting in a deadlock.The thread will be perpetually waiting for a signal that is never sent.Any mutex can be used, there is no explicit link between the mutex and the condition variable. Functions used in conjunction with the condition variable:
Example code: cond1.c Compile: cc -lpthread cond1.c Run: ./a.out Results: Note that functionCount1() was halted while count was between the values COUNT_HALT1 and COUNT_HALT2.The only thing that has been ensures is that functionCount2 will increment the count between the values COUNT_HALT1 and COUNT_HALT2. Everything else is random. The logic conditions (the 'if' and 'while' statements) must be chosen to insure that the 'signal' is executed if the 'wait' is ever processed.Poor software logic can also lead to a deadlock condition. Note: Race conditions abound with this example because count is used as the condition and can't be locked in the while statement without causing deadlock. I'll work on a cleaner example but it is an example of a condition variable.
When this option is enabled, each thread may have its own scheduling properties.Scheduling attributes may be specified:
