because job control is defined as mandatory on Issue 4 conforming implementations.
• Reference to implementation-dependent abnormal termination routines, such as creation of a core
file, in item ii in the defaults action list is marked as an extension.
Issue 4, Version 2
The following changes are incorporated for X/OPEN UNIX conformance:
• The SIGTRAP, SIGBUS, SIGSYS,
SIGPOLL, SIGPROF, SIGXCPU, SIGXFSZ, SIGURG, and
SIGVTALRM signals are added to the list of signals that will be supported on all conforming imple-
mentations.
• The sa_sigaction member is added to the
sigaction structure, and a note is added that the
storage used by sa_handler and sa_sigaction may overlap.
• The
SA_ONSTACK , SA_RESETHAND , SA_RESTART ,
SA_SIGINFO , SA_NOCLDWAIT ,
SS_ONSTACK , SS_DISABLE , MINSIGSTKSZ , and
SIGSTKSZ constants are defined. The
stack_t, sigstack, and siginfo structures are defined.
• Definitions are given for the
ucontext_t , stack_t, sigstack, and siginfo_t types.
• A table is provided listing macros that are defined as signal-specific reasons why a signal was gen-
erated. Signal-specific additional information is specified.
• The
bsd_signal() , killpg() , _longjmp() , _setjmp(), sigaltstack()
, sig-
hold()
, sigrelse(), sigset(), and sigstack() functions are added to the list of func-
tions declared in this header.
