③(*handler)(int)的右边没有符号,左边是void。综上,handler是一个指向返回void值的函数的指针。 2. void (*signal(int sig, void (*handler)(int)))(int): void (*handler)(int)在上面的步骤已经做了分析,我们可以使用语句typedef void (*handler)(int)将其简化(将handler声明为一个新的类型,这个类型...

The main() function of mt_with_handler.c starts as follows: sigset_t signal_set; sigemptyset(&signal_set); sigaddset(&signal_set, SIGINT); sigprocmask(SIG_BLOCK, &signal_set, NULL); What we do in the code snippet above, just at the beginning of main(), is to block SIGINT. After...
