NAME
signals - signal numbers
SYNOPSIS
#include <sys/signal.h>
#include <sys/ddi.h>
DESCRIPTION
There are two ways to send a signal to a process. The first,
psignal(D3), or, on multiprocessor systems, proc_signal(D3),
can be used by non-STREAMS drivers. The second, by using an
M_SIG or M_PCSIG message, can be used by STREAMS drivers and
modules.
The following is a list of the signals that drivers may send
to processes.
SIGHUP The device has been disconnected.
SIGINT The interrupt character has been received.
SIGQUIT The quit character has been received.
SIGPOLL A pollable event has occurred.
SIGTSTP Interactive stop of the process.
SIGURG Urgent data are available.
SIGWAITING All LWPs in a process are blocked.
SIGWINCH The window size has changed.
USAGE
The signal SIGTSTP cannot be generated with psignal or
proc_signal. It is only valid when generated from a stream.
