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...
There is a Posix Pthreads library available for use with MSVC/Intel-C, but it has, obviously, a CDECL interface. DD will have to weigh the costs of writing interfaces to these for use from Fortran. If any callback functions are going to be passed to the Posix routines, they will have...
调用wait()函数来同步并释放资源一样,线程之间也有类似的机制,那就是pthread_join()函数。pthread_join()可以将当前线程挂起,等待线程的结束,该函数是一个阻塞函数,调用它的...结束,使创建的线程有机会执行。所有线程都有一个线程号,也就是threadid,其类型为pthread_t,通过调用pthread_self()函数可以获得自身的线...
