信号机制是类UNIX体系中的一种重要的进程间通讯手法之一。咱们常常运用信号来向一个进程发送一个简略的音讯。例如:假定咱们发动一个进程经过socket读取长途主机发送过来的网络数据包,此刻因为网络要素当时主机还没有收到相应的数据,当时进程被设置为可中止等候状况(TASK_INTERRUPTIBLE),此刻咱们现已失掉耐性,想提前结束这个进程,所以能够经过kill指令想这个进程发送KILL信号,内核会唤醒该进程,履行它的信号处理函数,KILL信号的默许处理是退出该进程。当然并不是一定要进程处于TASK_INTERRUPTIBLE状况时才能够处理信号。

别的应用程序能够经过signal()等函数来为一个信号设置默许处理函数。例如当用户按下CTRL+C时,shell将会宣布SIGINT信号,SIGINT的默许处理函数是履行进程的退出代码,可是下面的比如把SIGINT的响应函数设置为int_handler。

[plain]view plaincopy

print?

  1. #include
  2. #include
  3. voidint_handler(intsignum)
  4. {
  5. printf(“\nSIGINTsignalhandler.\n”);
  6. printf(“exit.\n”);
  7. exit(-1);
  8. }
  9. intmain()
  10. {
  11. signal(SIGINT,int_handler);
  12. printf(“int_handlersetforSIGINT\n”);
  13. while(1)
  14. {
  15. printf(“gotosleep.\n”);
  16. sleep(60);
  17. }
  18. return0;
  19. }

当履行上面这段代码时,先履行main函数,设置SIGINT的处理函数,并进入睡觉状况,进程进入可中止等候状况:
