For UNIX systems, a standardized C language threads programming interface has been specified by the IEEE POSIX 1003.1c standard. Implementations that adhere to this standard are referred to as POSIX threads, or Pthreads. The tutorial begins with an introduction to concepts, motivations, and design...
retval - 返回线程的值。 此例程会终止线程。pthread_exit函数永远不会返回。如果未分离线程,则可以使用 pthread_join 从另一个线程检查线程 ID 和返回值。注意:返回指针 *retval 不得属于本地范围,否则一旦线程终止,它将不复存在。 转载于Linux Tutorial: POSIX Threads (cmu.edu) ...

The tutorial begins with an introduction to concepts, motivations, and design considerations for using Pthreads. Each of the three major classes of routines in the Pthreads API are then covered: Thread Management, Mutex Variables, and Condition Variables. Example codes are used throughout to demons...
