    sigset_t sigset; 
     
    sigfillset(&sigset);/*填充所有信号*/ 
     
    if(sigismember(&sigset,SIGINT))/*判断SIGINT*/ 
        printf("SIGINT exist in signal_set!\n"); 
    if(sigismember(&sigset,SIGTERM)) 
        printf("SIGTERM exist in signal_set!\n");    
    if(sigismember(&sigset,SIGABRT)) 
        printf("SIGABRT exist in signal_set!\n"); 
     if(sigdelset(&sigset,SIGINT)<0)/*移除SIGINT*/ 
        perror("del error\n"); 
        else 
            printf("SIGINT have been removed!\n"); 
     if(sigismember(&sigset,SIGINT))

<4>检测被搁置信号

Int sigpending(sigset_t *set);

返回对于调用进程被阻塞不能递送和当前未决的信号集.该信号集通过s e t参数返回.
