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

PROLOG         top

       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         top

       siglongjmp — non-local goto with signal handling

SYNOPSIS         top

       #include <setjmp.h>

       void siglongjmp(sigjmp_buf env, int val);

DESCRIPTION         top

       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         top

       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         top

       No errors are defined.

       The following sections are informative.

EXAMPLES         top

       None.

APPLICATION USAGE         top

       The distinction between setjmp() or longjmp() and sigsetjmp() or
       siglongjmp() is only significant for programs which use sigaction(),
       sigprocmask(), or sigsuspend().

RATIONALE         top

       None.

FUTURE DIRECTIONS         top

       None.
