1. SMP机器中实现并行常见的做法就是使用threads, hardware vendors有自己的threads实现,但是给程序移植带来很大问题。于是,对于UNIX系统来说,IEEE POSIX 1003.1c标准出台,这就是POSIX Threads -- pthread 2. 据我所知,有一个open source的项目,是一个library,实现了windows下的pthread,简单来说,将我们写的pthread的...
Pthreads are defined as a set of C language programming types and procedure calls, implemented with apthread.hheader/include file and a thread library - though this library may be part of another library, such aslibc. There are several drafts of the POSIX threads standard. It is important ...
在共享内存的多个处理器的结构上,threads可以被用来实现并行。从历史上看,硬件供应商已经实现了自己的线程专有版本,使移植成为软件开发人员关心的问题。在UNIX系统中,一个标准的C语言的多线程编程接口已经被IEEE POSIX 1003.1c标准规定。坚持这个标准的实现称为POSIX线程,或pthreads。

Interprocess Communication(IPC,进程间通信)在QNX Neutrino从一个嵌入式实时系统向一个全面的POSIX系统转变起着至关重要的作用。IPC是将在内核中提供各种服务的进程内聚在一起的粘合剂。在QNX中,消息传递是IPC的主要形式,也提供了其他的形式,除非有特殊的说明,否则这些形式也都是基于本地消息传递而实现的。 将更高级...
threads created. And if POSIX thread implementation is done in the user space alone, there are many issues that has to be dealt with. Let’s think that POSIX thread is implemented completely in the user space, so the scheduling of threads is to be done by the POSIX threads library itself...
