SIGLONGJMP(3P)          POSIX Programmer's ManualSIGLONGJMP(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_bufenv, intval);

DESCRIPTION        top

       Thesiglongjmp() function shall be equivalent to thelongjmp()       function, except as follows:        *  References tosetjmp() shall be equivalent tosigsetjmp().        *  Thesiglongjmp() function shall restore the saved signal mask           if and only if theenv argument was initialized by a call tosigsetjmp() with a non-zerosavemask argument.

RETURN VALUE        top

       Aftersiglongjmp() is completed, program execution shall continue       as if the corresponding invocation ofsigsetjmp() had just       returned the value specified byval.  Thesiglongjmp() function       shall not causesigsetjmp() to return 0; ifval 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 betweensetjmp() orlongjmp() andsigsetjmp() orsiglongjmp() is only significant for programs which usesigaction(),sigprocmask(), orsigsuspend().

RATIONALE        top

       None.

FUTURE DIRECTIONS        top

       None.
