1、爆代码

 

#include<setjmp.h>
#include<unistd.h>
#include<stdio.h>
#include<stdlib.h>void    f1(int, int, int, int);
void    f2(void);static jmp_buf jmpbuffer;
static int globval;
int i = 4;
int main(void)
{int     autoval;register int   regival;volatile int   volaval;static int statval;globval = 1; autoval = 2; regival = 3; volaval = 4; statval = 5;i = 5;int result = setjmp(jmpbuffer);if (result != 0) {printf("result is %d\n", result);printf("after longjmp:\n");printf("i is %d\n", i);printf("globval = %d, autoval = %d, regival = %d,"" volaval = %d, statval = %d\n",globval, autoval, regival, volaval, statval);exit(0);}else {puts("result == 0");}
