SIGLONGJMP(3P)             POSIX Programmer's Manual            SIGLONGJMP(3P)

PROLOG
       This  manual  page is part of the POSIX Programmer's Manual.  The Linux
       implementation of this interface may differ (consult the  corresponding
       Linux  manual page for details of Linux behavior), or the interface may
       not be implemented on Linux.
NAME
       siglongjmp - non-local goto with signal handling
SYNOPSIS
       #include <setjmp.h>
       void siglongjmp(sigjmp_buf env, int val);

DESCRIPTION
       The siglongjmp() function shall be equivalent to  the  longjmp()  func-
       tion, except as follows:
        * References to setjmp() shall be equivalent to sigsetjmp().
        * The siglongjmp() function shall restore the saved signal mask if and
          only if the env argument was initialized by a  call  to  sigsetjmp()
          with a non-zero savemask argument.
RETURN VALUE
       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.
ERRORS
       No errors are defined.
       The following sections are informative.
EXAMPLES
       None.
APPLICATION USAGE
       The distinction between setjmp() or longjmp() and sigsetjmp()  or  sig-
       longjmp()  is only significant for programs which use sigaction(), sig-
       procmask(), or sigsuspend().
RATIONALE
       None.
FUTURE DIRECTIONS
       None.
