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() function, 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  siglongjmp()  is  only
       significant for programs which use sigaction(), sigprocmask(), or sigsuspend().

RATIONALE

       None.

FUTURE DIRECTIONS

       None.
