15 The siglongjmp() function shall be equivalent to the longjmp() func‐
16 tion, except as follows:
17
18 * References to setjmp() shall be equivalent to sigsetjmp().
19
20 * The siglongjmp() function shall restore the saved signal mask if and
21 only if the env argument was initialized by a call to sigsetjmp()
22 with a non-zero savemask argument.
23
25 After siglongjmp() is completed, program execution shall continue as if
26 the corresponding invocation of sigsetjmp() had just returned the value
27 specified by val. The siglongjmp() function shall not cause sigsetjmp()
28 to return 0; if val is 0, sigsetjmp() shall return the value 1.

39 The distinction between setjmp() or longjmp() and sigsetjmp() or sig‐
40 longjmp() is only significant for programs which use sigaction(), sig‐
41 procmask(), or sigsuspend().
