POSIX Threads , usually referred to as pthreads , is an execution model that exists independently from a language, as well as a parallel execution model. It allows a program to control multiple different flows of work that overlap in time.
In my previous article , I talked about threaded code that did unusual and unexpected things.

Programming with POSIX Threads
POSIX Threads , usually referred to as pthreads , is an execution model that exists independently from a language, as well as a parallel execution model. It allows a program to control multiple different flows of work that overlap in time. It is implemented with a pthread. If a programmer wanted the threads to communicate with each other, this would require defining a variable outside of the scope of any of the functions, making it a global variable.
This program can be compiled using the gcc compiler with the following command:. Windows does not support the pthreads standard natively, therefore the Pthreads-w32 project seeks to provide a portable and open-source wrapper implementation. It can also be used to port Unix software which uses pthreads with little or no modification to the Windows platform.
The mingw-w64 project also contains a wrapper implementation of pthreads , winpthreads ,  which tries to use more native system calls than the Pthreads-w32 project.

POSIX threads explained, Part 2
It allows one to spawn a new concurrent process flow. It is most effective on 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 for the process. Parallel programming technologies such as MPI and PVM are used in a distributed computing 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 will be processed in the thread. This routine kills the thread.

Желая помочь, Беккер обратил их внимание на то, что все показанные ему иероглифы объединяет нечто общее - они одновременно являются и иероглифами кандзи. В комнате тут же стало тихо. Старший дешифровщик, нескладный тип по имени Морант, не выпускавший сигареты изо рта, недоверчиво уставился на Беккера.
Проклятие! - выругался он, потянувшись к телефону сквозь сплетение проводов.
