Explanation
The setjmp function is called in line 8. At this time, the environment in which the setjmp
function was called is saved in jmp_buf type variable env. The return value in this case is 0, and
therefore function sub is called next.
The environment saved in variable env is restored by the longjmp function called within function
sub. As a result, the program behaves just as if a return had been made from the setjmp function
in line 8. However, the return value at this time is the value (1) specified by the second parameter
of the longjmp function. As a result, execution proceeds from line 9.
