PROLOG

6       This  manual  page is part of the POSIX Programmer's Manual.  The Linux
7       implementation of this interface may differ (consult the  corresponding
8       Linux  manual page for details of Linux behavior), or the interface may
9       not be implemented on Linux.

NAME

13       siglongjmp — non-local goto with signal handling
14

SYNOPSIS

16       #include <setjmp.h>
17
18       void siglongjmp(sigjmp_buf env, int val);
19

DESCRIPTION

21       The siglongjmp() function shall be equivalent to  the  longjmp()  func‐
22       tion, except as follows:
23
24        *  References to setjmp() shall be equivalent to sigsetjmp().
25
26        *  The  siglongjmp()  function  shall restore the saved signal mask if
27           and only  if  the  env  argument  was  initialized  by  a  call  to
28           sigsetjmp() with a non-zero savemask argument.
29

RETURN VALUE

31       After siglongjmp() is completed, program execution shall continue as if
32       the corresponding invocation of sigsetjmp() had just returned the value
33       specified   by   val.    The  siglongjmp()  function  shall  not  cause
34       sigsetjmp() to return 0; if val is  0,  sigsetjmp()  shall  return  the
35       value 1.
36

ERRORS

APPLICATION USAGE

46       The  distinction  between setjmp() or longjmp() and sigsetjmp() or sig‐
47       longjmp() is only significant for programs which use sigaction(),  sig‐
48       procmask(), or sigsuspend().
49

RATIONALE

51       None.
52

FUTURE DIRECTIONS

54       None.
