Lets see if i understand how setjmp/longjmp works. Using the following
sample code down below, i would call some_function from my exit function.
The call to longjmp transfers control to the line
value=setjmp(environment_buffer) Inplace of the the printf, i would put my
handling code?
#include<setjmp.h>
#include<stdio.h>
void some_function(jmp_buf);
int main(void)
{
int value;
jmp_buf environment_buffer;
value=setjmp(environment_buffer);
if(value!=0)
{
printf("Reached this point from a longjmp with value=%d.\n",value);
exit(0);
}
printf("Calling function.\n");
some_function(environment_buffer);
return 0;
}
void some_function(jmp_buf env_buf)
{
longjmp(env_buf,5);
}
Thanks,
Andrew
