Programming with POSIX threads David R. Butenhof

The pthread is build on notion like Mutex ,Conditions Variable. To learn the fundamentals on POSIX Threads Programming, I will recommend you to go to following links. I learned thread programming with POSIX thread or pthread while I was C/C++ programmer long time ago. One of the key features of Goroutines is their cost; they are cheap to create in terms of initial memory footprint (as opposed to the 1 to 8 megabytes with a traditional POSIX thread) and their stack grows and shrinks as necessary. Most programmers have run into problems with infinite recursion before, and while it is fatal to their program, it isn't usually fatal to their machine. Pthread_cancel in POSIX thread. Here is an example to use pthread_cancel in POSIX thread programming. So, why are Go programs different ? The mutex is already locked by the same thread. This is simple: to make these function threads-safe in an effective manner, glibc uses a mutex. Java's synchronize, wait and notify always baffled me. See Butenhof's book, Programming with POSIX Threads, §6.6.4. In MacOS 10.6.6, a lock implementation is provided using the POSIX Threads API. In multithreaded programming, we often speak of locks (also known as mutexes).
