void longjmp (void *j_buf, short ret_val);

Performs nonlocal goto.

A call to longjmp restores the task state captured by the last call to setjmp with the argument j_buf. It then returns in such a way that setjmp appears to have returned with the value ret_val. j_buf is usually a buffer of type JMP_BUF. See setjmp for more info.
Note: longjmp should not be called with a value 0 as ret_val.
