We can execute a heavy query requested by the user, and still respond to Handling a user interface, and another thread handling database queries, Is that several operations may be carried out in parallel, and thus eventsĬan be handled immediately as they arrive (for example, if we have one thread
Array pthread c serial#
The advantage of using a thread group instead of a normal serial program The system has several processors, then really in parallel). All these threads execute in parallel (i.e. The same global variables, same heap memory, same set of file descriptors,Įtc. They all share the same memory, and thus can access
A Thread Group is a set of threads all executing With other threads (where as for processes we usually have a different memoryĪrea for each one of them). Unlike a real process, the thread normally shares its memory I'd try to check the example programs on other systems as well (Solaris 2.5Ĭomes to mind), to make it more "cross-platform".Ī thread is a semi-process, that has its own stack, and executes a given Work with user-level threading libraries (refer to our Some of the example programs are using blocking system calls, they won't

Should refer to their system's manuals in case of incompatibilities. Programmers with access to other systems, using different versions of pthreads, Written using a Linux system with the kernel-level LinuxThreads library, v0.5, Revised over a period of several years, one will find that implementationsĪdhering to different drafts of the standard have a different set of functions,ĭifferent default values, and different nuances. Of the POSIX threads standard shall be used?". When talking about POSIX threads, one cannot avoid the question "Which draft Models, such as those used in windowing environments (X, Motif), will find itĮasier to grasp the concepts of multi-threaded programming.
I would assume that users which are familiar with asynchronous programming To explain the theoreticl background and terms to those who are familiar only Programming (or multi-processing) concepts. There is an implicitĪssumption that the user has some theoretical familiarity with paralell

It explains theĭifferent tools defined by the library, shows how to use them, and then givesĪn example of using them to solve programming problems. How its features can be used in "real-life" programs.
