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

12       siglongjmp — non-local goto with signal handling
13

SYNOPSIS

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

DESCRIPTION

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

RETURN VALUE

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

ERRORS

37       No errors are defined.

APPLICATION USAGE

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

RATIONALE

50       None.
51

FUTURE DIRECTIONS

53       None.
