What happens when we longjmp into a function that has already returned?
#include <stdio.h>
#include <stdlib.h>
#include <setjmp.h>
static jmp_buf env;
int returnjump(int val)
{
printf("called into returnjump\n");
printf("in setjump %d\n",val*2);
setjmp(env);
return val;
}
int main(int argc, char *argv[])
{
int val1 = 5;
int val2 = 10;
int returnme=0;
/*
if(val1 == 5)
{
returnme=returnjump(val1);
setjmp(env);
printf("%d\n", returnme);
}
*/
if(val2 == 10)
{
returnme=returnjump(val2);
longjmp(env, 1);
printf("%d\n", returnme);
}
exit(EXIT_SUCCESS);
}
