pthread_testcancel用法简解
某些情况下，希望通过pthread_cancel结束某个线程，但是被结束的线程必须在某一个点来进行退出操作，就需要用到pthread_testcancel。

示例代码如下
 

#include <pthread.h>
#include <iostream>
#include <unistd.h>

using std::endl;
using std::cout;

void* test_cannel(void* arg)
{
  pthread_setcancelstate(PTHREAD_CANCEL_ENABLE,NULL);
  pthread_setcanceltype(PTHREAD_CANCEL_DEFERRED,NULL);
  while(true)
  {
    pthread_setcancelstate(PTHREAD_CANCEL_DISABLE,NULL);
    cout << "1" << endl;
    cout << "2" << endl;
    cout << "3" << endl;
    cout << "4" << endl;
    cout << "5" << endl;
    cout << "6" << endl;
    cout << "7" << endl;
    pthread_setcancelstate(PTHREAD_CANCEL_ENABLE,NULL);
    pthread_testcancel();
  }

}


void* test_no_cannel(void* arg)
{
  //pthread_setcanceltype(PTHREAD_CANCEL_ASYNCHRONOUS,NULL);
  while(true)
  {
    cout << "1" << endl;
    cout << "2" << endl;
    cout << "3" << endl;
    cout << "4" << endl;
    cout << "5" << endl;
    cout << "6" << endl;
    cout << "7" << endl;
    //sleep(1);
  }

}

int main()
{

  pthread_t p1;
  pthread_create(&p1,NULL,test_cannel,NULL);
  sleep(1);
  pthread_cancel(p1);
  pthread_join(p1,NULL);

  return 0;
}
