signal(3} signal(3}
SIGCONT 2ge continue after stop (cannot be blocked)
SIGURG 30e urgent condition present on socket
SIGIO 31. I/O is possible on a descriptor (see fcntl(2»
The starred signals in the above list cause a core image if not
caught or ignored (see below).
Signals marked with. are discarded if the action is SIG DFLi
signals marked with t cause the process to stop if the process is
part of 4.2 job control.
Junc is assigned one of three values: SIG DFL, SIG IGN, or a
Junction-address. The actions prescribed by these values are as
follows:
S I G _ D FL - terminate process upon receipt of a signal
Upon receipt of the signal sig, the receiving process is to be
terminated with the following consequences:
February, 1990
RevisionC
All of the receiving process's open file descriptors will
be closed.
If the parent process of the receiving process is executing
a wai t, it will be notified of the termination of the
receiving process and the terminating signal's number
will be made available to the parent process; see
wait(2).
If the parent process of the receiving process is not executing
a w ai t, the receiving process will be
transformed into a zombie process (see exi t(2) for
definition of zombie process).
The parent process ID of each of the receiving
process's existing child processes and zombie processes
will be set to 1. This means the initialization process
(see intro(2» inherits each of these processes.
Each attached shared memory segment is detached and
the value of shIn nattach in the data structure associated
with its shared memory identifier is decremented
by 1.
For each semaphore for which the receiving process
has set a semadj value (see semop(2», that semadj
value is added to the semval of the specified semaphore.
