siglongjmp - non-local goto with signal handling
The siglongjmp() function shall be equivalent to the longjmp() function, except as follows:
After siglongjmp() is completed, program execution shall continue as if the corresponding invocation of sigsetjmp() had just returned the value specified by val. The siglongjmp() function shall not cause sigsetjmp() to return 0; if val is 0, sigsetjmp() shall return the value 1.
No errors are defined.
The distinction between setjmp() or longjmp() and sigsetjmp() or siglongjmp() is only significant for programs which use sigaction(), sigprocmask(), or sigsuspend().

First released in Issue 3. Included for alignment with the ISO POSIX-1 standard.
The DESCRIPTION is updated for alignment with the POSIX Threads Extension.
The DESCRIPTION is rewritten in terms of longjmp().
The SYNOPSIS is marked CX since the presence of this function in the <setjmp.h> header is an extension over the ISO C standard.
