Motivated by the recent attention on superluminal phenomena, we investigate the compatibility between faster-than-c propagation and the fundamental principles of relativity and causality. We first argue that special relativity can easily accommodate—indeed, does not exclude—faster-than-c signaling at th...
与之一样有相同功能的命令是“display/i $pc” ,当运行完这个命令后,单步跟踪会在打出程序代码的同时打出机器指令(也就是汇编代码) 2)信号(Signals) 信号是一种软中断,是一种处理异步事件的方法。一般来说,操作系统都支持许多信号。尤其是UNIX,比较重要应用程序一般都会处理信号。UNIX定义了许多信号,比如SIGINT表...
Description:Signals are software interrupts delivered to a process by the operating system. Signals can also be issued by the operating system based on system or error conditions. There is a default behavior for some (i.e. a process is terminated when it receives an inturrupt SIGINT Note that...
void (*signal(int sig, void (*handler)(int)))(int) signal determines how subsequent signals will be handled. If handler is SIG_DFL, the implementation-defined default behavior is used, if it is SIG_IGN, the signal is ignored; otherwise, the function pointed to by handler will be called...

ANSI 4.7.1.1 The set of signals for the signal functionThe first argument passed to signal must be one of the symbolic constants described in the Run-Time Library Reference for the signal function. The information in the Run-Time Library Reference also lists the operating mode support for each...
Let’s explore the basics from a C perspective.The Signals API is in <signal.h>. Example usage:#include <signal.h> #include <stdio.h> void catch(int signo) { printf("Received signal %d\n", signo); } int main(void) { if (signal(SIGINT, catch) == SIG_ERR) { printf("Error ...
