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

implementations.

• 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

generated. 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-
