您可以在Linux和Windows中运行程序。 1、thread方法启动了新的线程，并返回了它的识别符。 该系统将使用传输的参数列表调用指定为函数参数的函数。...from _thread import start_new_thread from time import sleep threadId = 1 #线程计数器 waiting = 2 #2秒等待的时间... def factorial(n): global threadId rc = 0 if n < 1: # base case print("{...}: {}".format('\nThread', threadId )) threadId += 1 rc = 1 else: returnNumber
PTW32中pthread_t定义是一个结构，而WIN_PTHREADS则与linux版本的pthread定义一样，是个整数类型....而PTW32中的pthread_t则不行，所以PTW32中提供了函数pthread_getw32threadid_np用于从pthread_t中返回线程id. // PTW32版本pthread.h中pthread_getw32threadid_np...* Returns the win32 thread ID for POSIX thread. */ PTW32_DLLPORT DWORD PTW32_CDECL pthread_getw32threadid_np...所以在写跨平台的代码时要获取线程id,就要区别对待，如下： static inline unsigned int pthread_id() { #ifdef PTW32_VERSION return pthread_getw32threadid_np
, 可以通过pthread_self返回，此threadID是遵循POSIX的标准，和linux内核中定义的threadID是不一样的，待会通过实例说明 attr是创建此thread的属性，可以通过pthread_attr_init.../a.out pid=101104, tid=101104, threadID=140298706515776 thread_create success!...pthread_self返回的ID是遵循POSIX的标准，而gettid()返回的ID是linux内核自定义的 我们通过PS来看下进程和线程的关系 root@ubuntu:$ ps -eLf UID...linux就是通过这样的方式来实现用户线程的。这样一来父子进程共享了所有的资源，共享了所有的资源，则这就是线程。...但是linux内核没有线程的概念，内核中只认task_struct结构，只要是task_struct结构就可以参与调度。所以内核中并没有区分进程和线程。
使用kill -l查看linux中的信号。 这次还是使用USR1信号作为用户的定义信号，进行线程的通信。...} 31 32 class ThreadInterface 33 { 34 public: 35 void CreateThread(void* (*func)(void *),void *threadID...) 43 { 44 pthread_create(&m_pTread, NULL, func, threadID); 45 } 46 47 void ThreadInterface::WaitThread...pthread_join(m_pTread, NULL); 50 } 51 52 class Service 53 { 54 public: 55 static void* run(void *threadID...) 56 { 57 pthread_t *pTreadID = reinterpret_cast(threadID); 58 pthread_kill
