The stack context will be + invalidated if the function which called setjmp() returns. + +<h3>RETURN VALUE +</h3> It returns the value 0 if returning directly and non-zero + when returning from longjmp() using the saved context. + +<h3>CONFORMING TO +</h3> POSIX + +<h3>NOTES +</h3> POSIX does not specify if the signal context will be saved + or not. If you want to save signal masks, use + sigsetjmp(3). setjmp() makes programs hard to understand + and maintain.
